😀 Top 20 AWS Services Every DevOps Engineer Should Know 😀

AWS provides a wide range of services to help DevOps engineers build, deploy, and manage applications efficiently. Here are the top 20 AWS services that every DevOps engineer should be familiar with:

👉 Amazon EC2 (Elastic Compute Cloud): This is where you launch virtual servers, often called instances, to run your applications.
👉 Amazon S3 (Simple Storage Service): Use it for scalable storage and to host static websites or store data.
👉 AWS Lambda: Execute code in response to events without the need to manage servers.
👉 Amazon RDS (Relational Database Service): A managed database service for popular database engines like MySQL, PostgreSQL, and more.
👉 Amazon Route 53: AWS's domain name system (DNS) web service to route traffic to your applications.
👉 Amazon ECR ( Elastic Container Registry): A fully managed Docker container registry to store, manage, and deploy Docker container images.
👉 Amazon ECS (Elastic Container Service): For running, stopping, and managing Docker containers.
👉 Amazon EKS (Elastic Kubernetes Service): A managed Kubernetes service to orchestrate containers.
👉 AWS CodeDeploy: Automates application deployments to different compute services.
👉 AWS CodePipeline: A Continuous Integration/Continuous Deployment (CI/CD) service to build, test, and deploy code.
👉 Amazon CloudWatch: Provides monitoring and observability for AWS resources and applications.
👉 AWS CloudFormation: Lets you define and provision infrastructure as code using templates.
👉 AWS Elastic Load Balancing: Distributes incoming application traffic across multiple targets.
👉 AWS Identity and Access Management (IAM): Manages user and group permissions within AWS.
👉 AWS CloudTrail: Logs all API calls made on your account, helping with security and compliance.
👉 Amazon Cloud Front: A content delivery network (CDN) to distribute content globally with low latency.
👉 Amazon VPC (Virtual Private Cloud): Allows you to create isolated networks within AWS.
👉 AWS Elastic Beanstalk: A service for deploying and scaling web applications.

What is 𝐜𝐨𝐧𝐭𝐚𝐢𝐧𝐞𝐫𝐝 and how does docker 🐬 work?


When we use the 𝐃𝐨𝐜𝐤𝐞𝐫 𝐂𝐋𝐈 to create a container, the 𝐃𝐨𝐜𝐤𝐞𝐫 𝐜𝐥𝐢𝐞𝐧𝐭 changes the command into a 𝐑𝐄𝐒𝐓𝐟𝐮𝐥 𝐀𝐏𝐈. This API is then sent to the 𝐃𝐨𝐜𝐤𝐞𝐫 𝐃𝐚𝐞𝐦𝐨𝐧.

The Docker Daemon first checks if the image is already on the local system. If it's not, it downloads the image from the 𝐃𝐨𝐜𝐤𝐞𝐫 𝐫𝐞𝐠𝐢𝐬𝐭𝐫𝐲.

Once the image is downloaded,

It calls 𝐜𝐨𝐧𝐭𝐚𝐢𝐧𝐞𝐫𝐝 to start the container. Containerd converts the downloaded image into an 𝐎𝐂𝐈-𝐜𝐨𝐦𝐩𝐥𝐢𝐚𝐧𝐭 𝐛𝐮𝐧𝐝𝐥𝐞.

This bundle is then passed to 𝐜𝐨𝐧𝐭𝐚𝐢𝐧𝐞𝐫𝐝-𝐬𝐡𝐢𝐦, which calls 𝐫𝐮𝐧𝐂 to start the container and handle 𝐧𝐚𝐦𝐞𝐬𝐩𝐚𝐜𝐞𝐬 and 𝐜𝐠𝐫𝐨𝐮𝐩𝐬.

𝐑𝐮𝐧𝐂 uses 𝐥𝐢𝐛𝐜𝐨𝐧𝐭𝐚𝐢𝐧𝐞𝐫 to interact with the Linux kernel and manage containers.

DevOps Real-time scenarios - 5

🔴 Scenario 9: Release Management.

🔻 Issue: A major release causes unexpected issues in the production environment.

🟢 Resolution:

Feature Flags: Implement feature flags to toggle new features on and off, enabling easy rollbacks if issues arise.
Canary Releases: Deploy the new release to a subset of users to test its stability before a full rollout.
Blue-Green Deployments: Set up blue-green deployments to have two identical environments—one for the current version and one for the new version.
Rollback Plan: Always have a well-defined rollback plan in case issues arise after deployment.

---------------------------------------------

🔴 Scenario 10: Cloud Resource Cost Optimization.

🔻 Issue: Cloud resource costs are increasing beyond budgeted limits.

🟢 Resolution:

Cost Monitoring: Regularly monitor and analyze cloud resource usage and associated costs.
Auto-Scaling: Implement auto-scaling mechanisms to automatically adjust resources based on demand.
Resource Tagging: Use resource tagging to categorize and track resource usage for accurate cost allocation.
Reserved Instances: Utilize reserved instances or savings plans to reduce costs for long-running resources.
Resource Rightsizing: Analyze resource utilization and downsize or upscale resources as needed.

⚡️ 𝐂𝐨𝐦𝐩𝐨𝐧𝐞𝐧𝐭𝐬 𝐨𝐟 𝐌𝐢𝐜𝐫𝐨𝐬𝐞𝐫𝐯𝐢𝐜𝐞𝐬 𝐀𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭𝐮𝐫𝐞 ⚡️

Microservices architecture breaks down applications into smaller, independent services. Here's a rundown of the 𝟏𝟎 𝐤𝐞𝐲 𝐜𝐨𝐦𝐩𝐨𝐧𝐞𝐧𝐭𝐬 in this architecture:

1. 𝐂𝐥𝐢𝐞𝐧𝐭
These are the end-users who interact with the application via different interfaces like web, mobile, or PC.

2. 𝐂𝐃𝐍 (Content Delivery Network)
CDNs deliver static content like images, stylesheets, and JavaScript files efficiently by caching them closer to the user's location, reducing load times.

3. 𝐋𝐨𝐚𝐝 𝐁𝐚𝐥𝐚𝐧𝐜𝐞𝐫
It distributes incoming network traffic across multiple servers, ensuring no single server becomes a bottleneck and improving the application's availability and reliability.

4. 𝐀𝐏𝐈 𝐆𝐚𝐭𝐞𝐰𝐚𝐲
An API Gateway acts as an entry point for all clients, handling tasks like request routing, composition, and protocol translation, which helps manage multiple microservices behind the scenes.

5. 𝐌𝐢𝐜𝐫𝐨𝐬𝐞𝐫𝐯𝐢𝐜𝐞𝐬
Each microservice is a small, independent service that performs a specific business function. They communicate with each other via APIs.

6. 𝐌𝐞𝐬𝐬𝐚𝐠𝐞 𝐁𝐫𝐨𝐤𝐞𝐫
A message broker facilitates communication between microservices by sending messages between them, ensuring they remain decoupled and can function independently.

7. 𝐃𝐚𝐭𝐚𝐛𝐚𝐬𝐞𝐬
Each microservice typically has its own database to ensure loose coupling. This can involve different databases for different microservices

8. 𝐈𝐝𝐞𝐧𝐭𝐢𝐭𝐲 𝐏𝐫𝐨𝐯𝐢𝐝𝐞𝐫
This component handles user authentication and authorization, ensuring secure access to services.

9. 𝐒𝐞𝐫𝐯𝐢𝐜𝐞 𝐑𝐞𝐠𝐢𝐬𝐭𝐫𝐲 𝐚𝐧𝐝 𝐃𝐢𝐬𝐜𝐨𝐯𝐞𝐫𝐲
This system keeps track of all microservices and their instances, allowing services to find and communicate with each other dynamically.

10. 𝐒𝐞𝐫𝐯𝐢𝐜𝐞 𝐂𝐨𝐨𝐫𝐝𝐢𝐧𝐚𝐭𝐢𝐨𝐧 (e.g., Zookeeper)
Tools like Zookeeper help manage and coordinate distributed services, ensuring they work together smoothly.

Optimise your 🐬 docker image by 95% not just in size but also in security.


1. 𝗨𝘀𝗲 𝗠𝘂𝗹𝘁𝗶-𝗦𝘁𝗮𝗴𝗲 𝗯𝘂𝗶𝗹𝗱𝘀.

Stage 1 will build an artifact consisting of all the required libraries & dependencies. Stage 2 will use a slim/scratch base image and copy only the artifact from Stage 1 resulting in up to 95% less image size.

2. 𝗣𝗶𝗰𝗸 𝘀𝗹𝗶𝗺 𝘃𝗲𝗿𝗶𝗳𝗶𝗲𝗱 𝗯𝗮𝘀𝗲 𝗶𝗺𝗮𝗴𝗲𝘀.

Slim images don’t have any unnecessary components like shell utilities, libraries, or metadata. It will reduce the size and the attack surface area.

3. 𝗕𝗲𝗻𝗲𝗳𝗶𝘁 𝗳𝗿𝗼𝗺 𝘁𝗵𝗲 𝗟𝗮𝘆𝗲𝗿 𝗖𝗮𝗰𝗵𝗶𝗻𝗴.

Always order the instructions from least changing to most changing i.e. use COPY instruction much later in the Dockerfile.

4. 𝗨𝘀𝗲 𝗹𝗲𝘀𝘀 𝗹𝗮𝘆𝗲𝗿𝘀.

Commands like RUN COPY ADD create layers. Fewer layers = Small Size = Faster Build Times.

5. 𝗡𝗲𝘃𝗲𝗿 𝗿𝘂𝗻 𝗶𝗺𝗮𝗴𝗲𝘀 𝗮𝘀 𝘁𝗵𝗲 𝗿𝗼𝗼𝘁 𝘂𝘀𝗲𝗿.

By default, every image runs with root privileges, so make sure you run the image as a non-pseudo user[may break your application, some processes need root privileges]

6. 𝗦𝗰𝗮𝗻 𝗶𝗺𝗮𝗴𝗲𝘀 𝗳𝗼𝗿 𝘃𝘂𝗹𝗻𝗲𝗿𝗮𝗯𝗶𝗹𝗶𝘁𝗶𝗲𝘀 using tools like Trivy & Scout.

Avoid CRITICAL and HIGH vulnerabilities.

Tip: To see individual layers of an image use tools like Dive
