🤦‍♀️ Knowing this beforehand , rolling updates would have been a cake walk to understand & not to surprise why most preferred deployment type by Big Tech Giants 🚀🚀


🔎 Why are different types of deployment strategies used ?

Deployments types are decided based on various factors. including client unique requirements , flexibility , scalability , managing risk and much more !

✨ Let’s picturize it as you have multiple servers , but you need to upgrade their versions , at the same time make sure user experience is not hampered by, rolling update comes as saviour , one by one you can upgrade to required/ new version test it and bring it online , similarly you follow it for remaining ones

✨ You can incrementally bring all your servers to required state

📌 It proves to be a game changer as when one of your server is updating/ upgrading rest of the services are in places and users experience no downtime and gradually same follows till whole system is updated

Are you optimizing your kubernetes workloads for efficiency? One key aspect is controlling resource usage within pods to ensure optimal performance and resources utilization.

🔍 Resource Requests:
➖ Specify minimum CPU and memory requirements for pods.
➖ Helps Kubernetes scheduler make informed placement decisions.
➖ Ensures pods have necessary resources to run effectively.

📈 Resource Limits:
➖ Set upper bounds on CPU and memory usage.
➖ Prevents pods from monopolizing resources.
➖ Maintains stability and reliability across the cluster.

Crafting secure and scalable cloud applications on AWS requires a solid foundation. This post explores the essential building blocks that form a typical AWS end-to-end application architecture.

🔶 𝗘𝘀𝘀𝗲𝗻𝘁𝗶𝗮𝗹 𝗕𝘂𝗶𝗹𝗱𝗶𝗻𝗴 𝗕𝗹𝗼𝗰𝗸𝘀:

✔️ AWS VPC (Virtual Private Cloud): A secure, isolated neighborhood within the cloud is your VPC, housing all your application resources and providing a private network.

✔️ Subnets: These are sub-divisions within your VPC. They segment your network further, allowing you to isolate public-facing components from private ones.

✔️ Servers: The workhorses of your application. Web servers handle requests, application servers handle the logic. Run them on EC2 instances (flexible, separate, or combined).

✔️ RDS: This manages service stores your application's data. It offers a variety of database engine options and ensures reliability and scalability.

✔️ Load Balancer: It distributes incoming user requests across multiple EC2 instances, ensuring your application remains available and performs fine under heavy traffic.

✔️ Auto Scaling Group: An Auto Scaling Group scales your EC2 instances up or down based on predefined rules, ensuring your application can handle fluctuating loads with ease.

✔️ Security Groups: These are virtual firewalls for your EC2 instances. They control incoming and outgoing traffic, enforcing security and access restrictions.

✔️ Route 53: This is your domain name manager in the cloud. Route 53 directs users to your application's endpoint (often a Load Balancer) and allows you to register and manage your domain names.

🔶 𝗕𝗲𝗻𝗲𝗳𝗶𝘁𝘀 𝗼𝗳 𝗮 𝗪𝗲𝗹𝗹-𝗔𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝗲𝗱 𝗦𝗼𝗹𝘂𝘁𝗶𝗼𝗻

By leveraging these core components, you can design an AWS architecture that's:

✔️ Scalable: Easily adapts to accommodate growth in traffic and data.

✔️ Secure: Provides robust security measures to protect your application and data.

✔️ Highly Available: Ensures your application remains accessible even during failures.

🌐 AWS Disaster Recovery strategies 🌐

1️⃣. Backup:
This is the most basic level of disaster recovery readiness. It involves regular backups of data and systems, often stored offsite or in the cloud. In this context, "Back" likely refers to backing up data and systems to restore them in case of data loss or system failure.

2️⃣. Pilot Light:
This refers to a disaster recovery setup where essential systems are kept in a minimal operational state
In the event of a disaster, additional resources can be quickly provisioned to bring the system to full operational capacity. It's a step up from basic backup, offering a faster recovery time.

3️⃣.Warm Standby:
A warm standby site is a disaster recovery setup where duplicate hardware and infrastructure are maintained, but they are not actively processing data or serving users.
The infrastructure is configured and ready to take over in case the primary site fails. This setup typically involves periodic synchronization of data and configurations to reduce recovery time.

➡️Hot Site:
A hot site is a fully operational secondary data center or environment that mirrors the primary production environment. It is continuously updated and synchronized with the primary site in real-time or near real-time.
In the event of a disaster, operations can seamlessly switch to the hot site with minimal disruption, offering the shortest recovery time objective (RTO) and recovery point objective (RPO).

👉Continuous deployment as sumes that every product change or update is deployed automatically to production without any manual supervision from a DevOps engineer.

💡 Continuous Delivery:
- Automates the release process.
- Ensures readiness for deployment at any time.
- Allows manual deployment when needed.

💡 Continuous Deployment:
- Automates deployment of every successful code change.
- Directly deploys to production without human intervention.
- Requires high confidence in automated testing.

Jenkins is a popular automation server that can be used to automate the CI/CD pipeline. In this post we will learn how to use Jenkins to automate the following steps:

✅ Checkout code from version control: Jenkins can be configured to automatically checkout code from a version control system, such as GitHub.
✅ Compile code: Jenkins can use a variety of build tools, such as Maven or Gradle, to compile the code.
✅ Run unit tests: Jenkins can run unit tests to ensure that the code is working properly.
✅ Build a Docker image: Jenkins can build a Docker image from the compiled code.
✅ Push Docker image to registry: Jenkins can push the Docker image to a Docker registry, such as Docker Hub.
✅ Deploy to Kubernetes: Jenkins can notify Kubernetes of the new Docker image and deploy it to a Kubernetes cluster.

✔️ 𝗖𝗼𝗻𝘁𝗮𝗶𝗻𝗲𝗿 𝗢𝗿𝗰𝗵𝗲𝘀𝘁𝗿𝗮𝘁𝗶𝗼𝗻: Consider Kubernetes or Docker Swarm for managing containers at scale.

✔️ 𝗩𝗲𝗿𝘀𝗶𝗼𝗻𝗶𝗻𝗴 𝗮𝗻𝗱 𝗧𝗮𝗴𝗴𝗶𝗻𝗴: Always tag images with version numbers to ensure reproducibility.

✔️ 𝗛𝗲𝗮𝗹𝘁𝗵 𝗖𝗵𝗲𝗰𝗸𝘀: Implement health checks to monitor container status and reliability.

✔️ 𝗥𝗲𝘀𝗼𝘂𝗿𝗰𝗲 𝗟𝗶𝗺𝗶𝘁𝘀: Set resource constraints to prevent one container from hogging resources.

✔️ 𝗗𝗼𝗰𝗸𝗲𝗿𝗳𝗶𝗹𝗲 𝗕𝗲𝘀𝘁 𝗣𝗿𝗮𝗰𝘁𝗶𝗰𝗲𝘀: Optimize Dockerfiles by minimizing layers and using caching effectively.

✔️ 𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆: Regularly update images, scan for vulnerabilities, and follow security best practices.

1️⃣.𝙄𝙢𝙖𝙜𝙚𝘽𝙖𝙘𝙠𝙋𝙪𝙡𝙡𝙊𝙛𝙛 :-
We face this issue when the image is not present in registry or the given image tag is wrong.
Make sure you provide correct registry url, image name and image tag.

We might face authentication failures, when image is being stored in a private registry, make sure to create secret with private registry credentials and add created secret in Kubernetes Deployment File to pull docker image.

2️⃣.𝘾𝙧𝙖𝙨𝙝𝙇𝙤𝙤𝙥𝘽𝙖𝙘𝙠𝙊𝙛𝙛 :-
We face this issue when the process deployed inside container not running then the POD will be moved to CrashLoopBackOff.
POD might be running out of CPU or memory, POD should get enough resources allocated that’s cpu and memory for an application to be up and running, to fix that check in Resources Requests and Resources Limits.

3️⃣.𝙊𝙊𝙈 𝙆𝙞𝙡𝙡𝙚𝙙 - 𝙊𝙪𝙩 𝙊𝙛 𝙈𝙚𝙢𝙤𝙧𝙮 :-
We face this issue when PODs tries to utilise more memory than the limits we have set.
We can resolve it by setting appropriate resource request and resource limit.

4️⃣.𝙋𝙊𝘿 𝙎𝙩𝙖𝙩𝙪𝙨 – 𝙋𝙚𝙣𝙙𝙞𝙣𝙜 :-
When nodes might not be ready and required resources like CPU and Memory may not be available in nodes for the PODs to be up and running.

5️⃣.𝙋𝙊𝘿 𝙎𝙩𝙖𝙩𝙪𝙨 – 𝙒𝙖𝙞𝙩𝙞𝙣𝙜 :-
POD will be scheduled to a node but POD won’t be running in scheduled node.
We can fix this by providing correct image name, image tag and authentication to registry.

If service is already created and application is still not accessible, make sure application and service are deployed in same namespace.

7️⃣.𝙋𝙊𝘿 𝙎𝙩𝙖𝙩𝙪𝙨 – 𝙀𝙫𝙞𝙘𝙩𝙚𝙙 :-
We can resolve this by setting appropriate resource requests and resource limits for the PODs and having enough resources in worker nodes.
