Week 3:

DevOps has several components that must work in unison for a team to meet its objectives. A key element, which usually serves as the center of the DevOps “machinery,” is configuration management. In this week, we are going to enhance our automation with configuration management tool Ansible and we are going to configure and setup WEB, APP and DB components on servers.

Week 4:

While companies look to fix their application development processes by moving from waterfall to DevOps, they also understand that DevOps alone won't save them. The latency in making capital purchases of hardware and software slows the development process, even if it's made agile. Developers end up waiting around for capital resources to be put in place before the applications can be deployed. Thus, DevOps won't have much value without the cloud, and the cloud won't have much value without DevOps. The centralized nature of cloud computing provides DevOps automation with a standard and centralized platform for testing, deployment, and production. During this week we are going to setup our project with multiple environments and we use Elastic Beanstalk service to replicate the same thing in AWS Cloud. Along with that we also discuss about restricting the users to use particular services in AWS using IAM and manage the servers with AWS systems manager which is an alternative to Ansible in cloud. Also we will talk about basic monitoring and log monitoring using ELK.

• Using CloudWatch as an alternative to log monitoring

Week 5:

Continuous Integration and Continuous Delivery (CI/CD) are often cited as pillars of successful DevOps. To establish and optimize the CI/CD development model and reap the benefits, companies need to build an effective pipeline to automate their build, integration and testing processes. At a high level, the pipeline “includes compiling, packaging, and running basic tests prior to a code base merge. After your code is in the base, the main branch of your version control software, additional tests are run to ensure your apps work with real configuration and other services. Performance and security tests are also run at this point. From here you deploy code to staging and then to production”. In this week, we are going to cover the tools which help in making the pipelines to deliver the code to production in smooth manner. We use GIT branching strategies, We talk about build tools like Maven and Gradle, We talk about functional testing using Selenium and Python code, We use CodeQuality testing using SonarQube, We talk about Nexus artifact manager and GitLab tool a bit more. Majorly we cover Jenkins Pipeline code and Seed Jobs in Jenkins for complete automation.

Week 6:

Continuous Integration and Continuous Delivery (CI/CD) techniques enable collaboration, increase agility, and deliver a high-quality product faster. It has never been easier to Integrate a Continuous Integration and Delivery pipeline without Cloud technologies. DevOps automation is becoming cloud-centric. Most public and private cloud computing providers support DevOps systemically on their platform, including continuous integration and continuous development tools. This tight integration lowers the cost associated with on-premises DevOps automation technology, and provides centralized governance and control for a sound DevOps process. Many developers who enter the process find that governance keeps them out of trouble, and it's easier to control this centrally via the cloud versus attempting to bring departments under control. In before week we have discussed the pipeline setups using different tools and we will replace them with AWS Services in this week. We are going to use S3 buckets as artifact repository, we use Code Commit as our GIT repository, we use CodeBuild instead of Jenkins Builds, we use Code Deploy instead of Ansible, we use Code Pipeline instead of Jenkins Pipelines.

Week 7:

Nowadays it’s critical to get your releases out fast, which requires having an automated CI/CD pipeline that takes your code from text to binaries to a deployed environment. Implementing an automated pipeline in the past has been challenging, especially when dealing with legacy applications. This is where Dockers and Kubernetes comes in. Kubernetes has revolutionized the way we deploy and manage our containerized applications. Using Helm together with Kubernetes, you gain simplified application deployment. Kubernetes is one of modern DevOps tools and component you require from infra side is declarative. Using DevOps tools, we reduced the deployments from days to hours and tools like kubernetes bring them to minutes. In this week, we are going to discuss about containerization technologies and basics of Docker. Then we are going to talk on kubernetes in a much-detailed way and we will complete all the CICD setups with Jenkins Kubernetes integrations.

Week 8:

Infrastructure as Code (IaC) is the management of infrastructure (networks, virtual machines, load balancers, and connection topology) in a descriptive model, using the same versioning as DevOps team uses for source code. Like the principle that the same source code generates the same binary, an IaC model generates the same environment every time it is applied. IaC is a key DevOps practice and is used in conjunction with continuous delivery. Tools like Terraform, AWS CloudFormation, Azure Resource Manager Templates, Google Cloud Deployment Manager Templates and OpenStack Heat are a great way to define server infrastructure for deploying software. The configuration to provision, modify, and rebuild an environment is captured in a way that is transparent, repeatable, and testable. Used right, these tools give us confidence to tweak, change, and refactor our infrastructure easily and comfortably. During this week, we are going to provision all the AWS services using Terraform and we going to exclusively include IAC in our CICD process and we will deliver the release in blue-green deployments without any outage to the end customer.
