If you've ever worked with AWS EC2 instances, you know that keeping your instance secure is crucial. One way to do this is by managing your firewall, and in this blog post, well go over how to configure UFW (Uncomplicated Firewall) on your EC2 instance to allow specific ports—like SSH (port 22), MySQL (port 3306), and HTTP (port 80)—so you can connect to your instance and run services smoothly.

Why Use UFW?#

On Ubuntu and other Debian-based systems, UFW is a straightforward command-line interface for controlling firewall rules. Because it is easy to set up and still provides a high degree of security, it is ideal for EC2 instances. Allowing the traffic you require while keeping unnecessary ports open to the internet is the aim here.

Prerequisites#

Before diving in, make sure:

• Your EC2 instance is running Ubuntu or another Debian-based Linux distribution.
• You have SSH access to the instance.
• UFW is installed (well check and install it if necessary).

Step-by-Step Guide to Open Ports#

1. Check if UFW is Installed#

First, let's check if UFW is installed on your EC2 instance. Connect to your EC2 instance and run:

If UFW is not installed, the command will return:

In that case, install it with:

2. Allow Specific Ports#

Now, let's open the ports you need:

These commands let traffic through on the specified ports, ensuring smooth access to your instance.

3. Enable UFW#

If UFW is not already enabled, activate it by running:

To verify, check the status:

You should see:

4. Optional: Restrict Access to Specific IPs#

You may want to restrict access to particular IPs for extra security. For instance, to only permit SSH from your IP:

You can do the same for MySQL and HTTP:

This adds an extra layer of security by preventing unwanted access.

5. Verify Your Firewall Rules#

Run the following command to check active rules:

This confirms which ports are open and from which IPs they can be accessed.

Troubleshooting Common Issues#

Can't Connect via SSH?#

If you cant connect to your EC2 instance via SSH after enabling UFW, make sure port 22 is open:

Also, check your AWS Security Group settings and ensure SSH is allowed. You can review AWS security group rules here.

Can't Connect to MySQL?#

Ensure port 3306 is open and verify that your database allows remote connections.

Web Traffic Not Reaching the Instance?#

Check if port 80 is open and confirm that your EC2 security group allows inbound HTTP traffic.

Conclusion#

You now know how to use UFW to open particular ports on your EC2 instance, enabling HTTP, MySQL, and SSH communication while restricting access to unwanted ports. This keeps your server safe while guaranteeing that critical services run correctly.

Have you ever been trying to do anything on AWS and been baffled by an error message that leaves you baffled? Often, the dreaded "not authorised to perform" error is the culprit. Usually, this occurs when a position or user lacks the authorisation needed to carry out a certain task. Have you ever witnessed anything similar to:

You're not alone, so don't worry! We'll explore the meaning of this error, its causes, and—above all—how to resolve it in this piece.

What's Happening Here?#

The problem message is rather simple: The role or user you are working with does not possess the necessary authorisation to establish a new IAM role. The issue indicates that there is no policy associated with the user or role that permits the action iam:CreateRole, which is strictly restricted.

One of AWS's most effective tools for managing access to AWS resources is Identity and Access Management (IAM). However, great power also comes with great responsibility, and if you're not cautious, controlling permissions can get a little complicated. There is obviously a missing component in your AWS setup, as shown by the error message you are viewing.

When Do You Run Into This Issue?#

You'll typically run into the "not authorized to perform iam:CreateRole" issue in the following scenarios:

Creating a New IAM Role for a Service or User#

Creating a new role could be necessary when configuring an AWS service (such as AWS CodeBuild, AWS Lambda, or Amazon EC2) that needs a particular IAM role for rights. This error occurs when a person or service tries to create that role without having the iam:CreateRole permissions.

Example: Trying to set up a CodeBuild project that requires a service role, but the user doesn't have permission to create that role.

Setting Up Automation or CI/CD Pipelines#

IAM roles may need to be created dynamically if you're automating infrastructure provisioning with a CI/CD pipeline (like Terraform or AWS CodePipeline). This error may occur if the pipeline's IAM role lacks the iam:CreateRole authorisation.

Example: Using a script that triggers AWS CloudFormation to create new resources but fails to create a role because the IAM role executing the script doesn't have iam:CreateRole.

Assigning or Modifying Service Roles#

If the user is unable to establish roles in IAM, a permission error may occur when you attempt to assign an existing role to the service or create a new role while working with services that must assume certain IAM roles, like AWS Lambda or Amazon ECS.

Example: Assigning a service role to a new EC2 instance but the user trying to do this doesn't have the iam:CreateRole permission.

Permissions Related to Infrastructure as Code (IaC) Tools#

IAM role generation is managed by a number of infrastructure tools, such as Terraform, CloudFormation, or AWS CDK. This error will appear if you use any of these tools to generate resources that need new IAM roles and the user isn't authorised to create roles.

Example: Running a terraform apply command that tries to create new IAM roles as part of an infrastructure change, but the user running the command doesn't have permission to create roles.

Cross-Account Role Creation#

You may attempt to create roles in one AWS account from another if you're dealing with multiple accounts (for instance, creating a cross-account role). The iam:CreateRole operation will be rejected if the second account's IAM user lacks the authority to create roles in the first account.

Example: Trying to create a role in Account A using a user from Account B, but the user doesn't have cross-account permissions to create roles in Account A.

The Fix: Adding the Right Permission#

To solve this, you'll need to make sure the user or role has the correct permissions attached to it. Here's how:

Locate the Role or User#

First, figure out which role or user is running into the issue. In this case, it's arn:aws:sts::123456789012:assumed-role/role-name/username. You can find this in your IAM dashboard on the AWS console.

Check the Policies#

Next, take a look at the IAM policies attached to that role or user. Policies define what actions are allowed or denied. In this case, you need to ensure that the policy allows the iam:CreateRole action.

Update the Policy#

If the permission is missing, you'll need to add a new policy or update an existing one. Here's an example of what the policy might look like to allow creating roles:

This policy gives permission to create roles for the specified resource (in this case, some-role). You can apply this to the user or role in question.

Things to Keep in Mind#

If you're still having trouble after adding the right policy, there are a few other things to check:

• Permission Boundaries: Strict permission boundaries can occasionally restrict the actions of AWS users or roles.
• Service Control Policies (SCPs): Check for SCPs that prevent iam:CreateRole from being used.
• Session Policies: Ensure no restrictive session policies are blocking the action.

Conclusion#

Managing IAM permissions in AWS can be tricky, but by following best practices, troubleshooting errors like iam:CreateRole becomes easier. Grant the least privilege necessary, use roles over users, and keep policies up to date.

Step-by-Step Guide to Multi-Cloud Automation with SkyPilot on AWS Step-by-Step Guide to Multi-Cloud Automation with SkyPilot on AWs

When it comes to administering cloud servers, there's nothing quite like trying to SSH into your EC2 instance and receiving the dreaded Connection rejected message. Prepare to panic! But take a deep breath—we've all been there, and the solution is frequently simpler than it appears. Let's troubleshoot this problem together, keeping it light but technical.

Why is My EC2 Ignoring Me?#

Before we get into the answer, let's quickly explore why your instance may be giving you the silent treatment:

• It's Alive... Right?
  • Perhaps the instance is turned off or failing its status checks. There is no machine and therefore no connection.

• Locked Door: Security Group Issues
  • Your security group ((EC2's way of saying firewall rules))[https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-security-groups.html] might not be letting you in.

• The Wrong Address
  • If you do not have an Elastic IP attached, your public IP address may vary. Are you knocking on the wrong door?

• Software Drama
  • SSH service might not be running, or the instance's firewall (hello, iptables) could be blocking port 22.

• Hardware Drama
  • Rare, but hardware issues or improper disk configurations can lead to this. Did you edit /etc/fstab recently?

Let's Fix It! (Step-by-Step)#

Step 1: Breathe.#

You're not locked out indefinitely. AWS gives us plenty of tools to recover access.

Step 2: Check if the Instance is Running#

Log into the AWS Management Console and head to the EC2 Dashboard:

• Is your instance in the Running state?
• Are the status checks green? If they're red, AWS may already be indicating a hardware or configuration issue.

Step 3: Review Security Group Rules#

Imagine going up to a party with the wrong invitation. Security groups are your EC2's bouncers, deciding who gets in.

• Go to Security Groups in the AWS Console.

Make sure there's an inbound rule allowing SSH (port 22) from your IP:

Type: SSH
Protocol: TCP
Port Range: 22
Source: Your IP (or 0.0.0.0/0 for testing—just don't leave it open forever!)

Step 4: Confirm the Public IP or DNS#

Every instance has an address, but it may vary unless you've configured an Elastic IP. Make sure you're using the right public IP/DNS name.

Run the SSH command:

Step 5: Test Your Key and Permissions#

Your private key file (.pem) is like a VIP pass. Without proper permissions, it won't work. Ensure it's secure:

Retry SSH.

Step 6: The Firewall's Watching Too#

Once inside the instance, check if the OS's internal firewall is behaving:

If you see rules blocking port 22, adjust them:

Step 7: Is SSH Even Running?#

If your EC2 is a house, the SSH daemon (sshd) is the butler answering the door. Make sure it's awake:

If it's not running:

But What if It's REALLY Bad?#

Sometimes the problem is deeper. Maybe you misconfigured /etc/fstab or the instance itself is inaccessible. Don't sweat it—AWS has your back: Use EC2 Instance Connect: A browser-based SSH client for emergencies. Attach the Volume to Another Instance: Detach the root volume, fix the configuration, and reattach it.

The Takeaway#

AWS EC2 instances are powerful, but they are not immune to minor issues. Whether it's a misconfigured firewall or a stopped SSH service, remedies are always available. And, hey, the next time Connection rejected appears, you'll know just how to convince your instance to open the door again. Enjoy cloud computing!

DynamoDB Streams and AWS Lambda can be integrated to create effective serverless apps that react to changes in your DynamoDB tables automatically. Developers frequently run into problems with this integration when the Lambda function is not called as intended. We'll go over how to troubleshoot and fix scenarios where your DynamoDB Stream isn't triggering your Lambda function in this blog article.

What Is DynamoDB Streams?#

Data changes in your DynamoDB table are captured by DynamoDB Streams, which enables you to react to them using a Lambda function. Every change (like INSERT, UPDATE, or REMOVE) starts the Lambda function, which can then analyze the stream records to carry out other functions like data indexing, alerts, or synchronization with other services. Nevertheless, DynamoDB streams occasionally neglect to call the Lambda function, which results in the modifications going unprocessed. Now let's explore the troubleshooting procedures for this problem.

1. Ensure DynamoDB Streams Are Enabled#

Making sure DynamoDB Streams are enabled for your table is the first step. The Lambda function won't get any events if streams aren't enabled. Open the Management Console for AWS. Go to Your Table > DynamoDB > Tables > Exports and Streams. Make sure DynamoDB Streams is enabled and configured to include NEW_IMAGE at the very least. Note: What data is recorded depends on the type of stream view. Make sure your view type is NEW_IMAGE or NEW_AND_OLD_IMAGES for a typical INSERT operation.

2. Check Lambda Trigger Configuration#

A common reason for Lambda functions not being invoked by DynamoDB is an improperly configured trigger. Open the AWS Lambda console. Select your Lambda function and navigate to Configuration > Triggers. Make sure your DynamoDB table's stream is listed as a trigger. If it's not listed, you'll need to add it manually: Click on Add Trigger, select DynamoDB, and then configure the stream from the dropdown. This associates your DynamoDB stream with your Lambda function, ensuring events are sent to the function when table items change.

3. Examine Lambda Function Permissions#

To read from the DynamoDB stream, your Lambda function needs certain permissions. It won't be able to use the records if it doesn't have the required IAM policies.

Ensure your Lambda function's IAM role includes these permissions:

Lambda can read and process records from the DynamoDB stream thanks to these actions.

4. Check for CloudWatch Logs#

Lambda logs detailed information about its invocations and errors in AWS CloudWatch. To check if the function is being invoked (even if it's failing):

1. Navigate to the CloudWatch console.
2. Go to Logs and search for your Lambda function's log group (usually named /aws/lambda/<function-name>).
3. Look for any logs related to your Lambda function to identify issues or verify that it's not being invoked at all.

Note: If the function is not being invoked, there might be an issue with the trigger or stream configuration.

5. Test with Manual Insertions#

Use the AWS console to manually add an item to your DynamoDB table to see if your setup is functioning: Click Explore table items under DynamoDB > Tables > Your Table. After filling out the required data, click Create item and then Save. Your Lambda function should be triggered by this. After that, verify that the function received the event by looking at your Lambda logs in CloudWatch.

6. Verify Event Structure#

Your Lambda function's handling of the incoming event data may be the problem if it is being called but failing. Make that the code in your Lambda function is handling the event appropriately. An example event payload that Lambda gets from a DynamoDB stream is as follows:

Make sure this structure is handled correctly by your Lambda function. Your function won't process the event as intended if the NewImage or Keys section is absent from your code or if the data format is off. Lambda code example Here is a basic illustration of how to use your Lambda function to handle a DynamoDB stream event:

7. Check AWS Region and Limits#

Make sure the Lambda function and your DynamoDB table are located in the same AWS region. The stream won't activate the Lambda function if they are in different geographical locations. Check the AWS service restrictions as well: Lambda concurrency: Make that the concurrency limit isn't being reached by your function. Throughput supplied by DynamoDB: Your Lambda triggers may be missed or delayed if your DynamoDB table has more read/write capacity than is allocated.

8. Retry Behavior#

There is an inherent retry mechanism in lambda functions that are triggered by DynamoDB Streams. AWS may eventually stop retrying if your Lambda function fails several times, depending on your configuration. To guarantee that no data is lost during processing, make sure your Lambda function retries correctly and handles mistakes graciously.

Conclusion#

A misconfiguration in the stream settings, IAM permissions, or event processing in the Lambda code may be the cause if DynamoDB streams are not triggering your Lambda function. You should be able to identify and resolve the issue by following these procedures and debugging the problem with CloudWatch Logs. The most important thing is to make sure your Lambda function has the required rights to read from the DynamoDB stream and handle the event data appropriately, as well as that the stream is enabled and connected to your Lambda function. Enjoy your troubleshooting!

You might eventually need to swap out an old Domain Controller (DC) for a new one when maintaining a network architecture. Decommissioning an outdated DC and installing a new one with DNS capability may be part of this procedure. The procedure is simple for those using AWS EC2 instances for this purpose, but it needs to be carefully planned and carried out. A high-level method to successfully managing this shift can be found below.

1. Install the New Domain Controller (DC) on a New EC2 Instance#

In order to host your new Domain Controller, you must first establish a new EC2 instance.

• EC2 Instance Setup: Begin by starting a fresh Windows Server-based EC2 instance. For ease of communication, make sure this instance is within the same VPC or subnet as your present DC and is the right size for your organization's needs.

• Install Active Directory Domain Services (AD DS): Use the Server Manager to install the AD DS role after starting the instance.

• Promote to Domain Controller: After the server has been promoted to a Domain Controller, the AD DS role must be installed. You will have the opportunity to install the DNS server as part of this promotion procedure. In order to manage the resolution of your domain name, this is essential.

2. Replicate Data from the Old DC to the New DC#

Making ensuring all of the data from the old DC is copied onto the new server is the next step once the new DC is promoted.

• Enable Replication: Active Directory will automatically replicate the directory objects, such as users, machines, and security policies, while the new Domain Controller is being set up. If DNS is set up on the old server, this will also include DNS records.

• Verify Replication: Ascertain whether replication was successful. Repadmin and dcdiag, two built-in Windows utilities, can be used to monitor and confirm that the data has been fully synchronized between both controllers.

3. Verify the Health of the New DC#

Before decommissioning the old Domain Controller, it is imperative to make sure the new one is completely functional.

• Use dcdiag: This utility examines the domain controller's condition. It will confirm that the DC is operating as it should.

• To make sure no data or DNS entries are missing, use the repadmin utility to verify Active Directory replication between the new and old DCs.

4. Update DNS Settings#

You must update the DNS settings throughout your network after making sure the new DC is stable and replicating correctly.

• Update VPC/DHCP DNS Settings: If you're using DHCP, make sure that the new DC's IP address is pointed to by updating the DNS settings in your AWS VPC or any other DHCP servers. This enables clients on your network to resolve domain names using the new DNS server.

• Update Manually Assigned DNS: Make sure that any computers or programs that have manually set up DNS are updated to resolve DNS using the new Domain Controller's IP address.

5. Decommission the Old Domain Controller#

It is safe to start decommissioning the old DC when the new Domain Controller has been validated and DNS settings have been changed.

• Demote the Old Domain Controller: To demote the old server, use the dcpromo command. With this command, the server no longer serves as a Domain Controller in the network and is removed from the domain.

• Verify Decommissioning: After demotion, examine the AD structure and replication status to make sure the previous server is no longer operating as a DC.

6. Clean Up and DNS Updates#

With the old DC decommissioned, there are some final cleanup tasks to ensure smooth operation.

• Tidy Up DNS and AD: Delete from both DNS and Active Directory any last traces of the previous Domain Controller. DNS entries and metadata are examples of this.

• Verify Client DNS Settings: Verify that every client computer is correctly referring to the updated DNS server.

Assigning IP Addresses to the New EC2 Instance#

You must make sure that your new DC has a stable IP address because your previous DC was probably linked to a particular one.

• Elastic IP Assignment: The new EC2 instance can be given an elastic IP address, which will guarantee that it stays the same IP throughout reboots and session restarts. By doing this, DNS resolution and domain service interruptions are prevented.

• Update Routing if Needed: Verify that the new Elastic IP is accessible and correctly routed both inside your VPC and on any other networks that communicate with your domain.

  Additional Considerations#

• Networking Configuration: Ascertain that your EC2 instances are correctly networked within the same VPC and that the security groups are set up to permit the traffic required for AD DS and DNS functions.

• DNS Propagation: The time it takes for DNS to propagate may vary depending on the size of your network. Maintain network monitoring and confirm that all DNS modifications have been properly distributed to clients and external dependencies.

Conclusion#

You can completely decommission your old Domain Controller located on an EC2 instance and install a new one with a DNS server by following these instructions. This procedure permits the replacement or enhancement of your underlying hardware and software infrastructure while guaranteeing little downtime and preserving the integrity of your Active Directory system. Your new EC2 instance can be given a static Elastic IP address, which will guarantee DNS resolution stability even when the server restarts.

There are several definitions of DevOps, and many of them sufficiently explain one or more characteristics that are critical to finding flow in the delivery of IT services. Instead of attempting to provide a complete description, we want to emphasize DevOps principles that we believe are vital when adopting or shifting to a DevOps method of working.

What is DevOps?#

DevOps is a software development culture that integrates development, operations, and quality assurance into a continuous set of tasks (Leite et al., 2020). It is a logical extension of the Agile technique, facilitating cross-functional communication, end-to-end responsibility, and cooperation. Technical innovation is not required for the transition to DevOps as a service.

Principles of DevOps#

DevOps is a concept or mentality that includes teamwork, communication, sharing, transparency, and a holistic approach to software development. DevOps is based on a diverse range of methods and methodologies. They ensure that high-quality software is delivered on schedule. DevOps principles govern the service providers such as AWS Direct DevOps, Google Cloud DevOps, and Microsoft Azure DevOps ecosystems.

Principle 1 - Customer-Centric Action#

Short feedback loops with real consumers and end users are essential nowadays, and all activity in developing IT goods and services revolves around these clients.

To fulfill these consumers' needs, DevOps as a service must have : - the courage to operate as lean startups that continuously innovate, - pivot when an individual strategy is not working - consistently invest in products and services that will provide the highest degree of customer happiness.

AWS Direct DevOps, Google Cloud DevOps, and Microsoft Azure DevOps are customer-oriented DevOps.

Principle 2 - Create with the End in Mind.#

Organizations must abandon waterfall and process-oriented models in which each unit or employee is responsible exclusively for a certain role/function and is not responsible for the overall picture. They must operate as product firms, with an explicit focus on developing functional goods that are sold to real consumers, and all workers must share the engineering mentality necessary to imagine and realise those things (Erich, Amrit and Daneva, 2017).

Principle 3 - End-to-end Responsibility#

Whereas conventional firms build IT solutions and then pass them on to Operations to install and maintain, teams in a DevOps as a service are vertically structured and entirely accountable from idea to the grave. These stable organizations retain accountability for the IT products or services generated and provided by these teams. These teams also give performance support until the items reach end-of-life, which increases the sense of responsibility and the quality of the products designed.

Principle 4 - Autonomous Cross-Functional Teams#

Vertical, fully accountable teams in product organizations must be completely autonomous throughout the whole lifecycle. This necessitates a diverse range of abilities and emphasizes the need for team members with T-shaped all-around profiles rather than old-school IT experts who are exclusively informed or proficient in, say, testing, requirements analysis, or coding. These teams become a breeding ground for personal development and progress (Jabbari et al., 2018).

Principle 5 - Continuous Improvement#

End-to-end accountability also implies that enterprises must constantly adapt to changing conditions. A major emphasis is placed on continuous improvement in DevOps as a service to eliminate waste, optimize for speed, affordability, and simplicity of delivery, and continually enhance the products/services delivered. Experimentation is thus a vital activity to incorporate and build a method of learning from failures. In this regard, a good motto to live by is "If it hurts, do it more often."

Principle 6 - Automate everything you can#

Many firms must minimize waste to implement a continuous improvement culture with high cycle rates and to develop an IT department that receives fast input from end users or consumers. Consider automating not only the process of software development, but also the entire infrastructure landscape by constructing next-generation container-based cloud platforms like AWS Direct DevOps, Google Cloud DevOps, and Microsoft Azure DevOps that enable infrastructure to be versioned and treated as code (Senapathi, Buchan and Osman, 2018). Automation is connected with the desire to reinvent how the team provides its services.

Remember that a DevOps Culture Change necessitates a Unified Team.#

DevOps is just another buzzword unless key concepts at the foundation of DevOps are properly implemented. DevOps concentrates on certain technologies that assist teams in completing tasks. DevOps, on the other hand, is first and foremost a culture. Building a DevOps culture necessitates collaboration throughout a company, from development and operations to stakeholders and management. That is what distinguishes DevOps from other development strategies.

Remember that these concepts are not fixed in stone while shifting to DevOps as a service. DevOps Principles should be used by AWS Direct DevOps, Google Cloud DevOps, and Microsoft Azure DevOps according to their goals, processes, resources, and team skill sets.
