Localize content Devops
- 1. Localize Content Devops everything which keeps us running https://localizecontent.com/
- 2. What is DevOps? Collaboration and communication of both developers and Ops. Automating the process of software delivery and infrastructure changes Building environment where building, testing, and releasing software, can happen rapidly, frequently, and more reliably
- 3. Objective Understand infrastructure Server Configuration Deployment of servers Collect and aggregate system as well as application logs Monitoring
- 4. Infrastructure Godaddy Nginx EC2 ECS RDS And lot more with AWS and separate
- 6. Code Github Build Using build process depends on framework Test Testing Deploy Scripts/CI ProvisionDeploy Monitor CloudWatch
- 7. Code Push Build and send image to ECR Deploy to ECS from ECR Deploy on machines Developer Github EC2 Code Pull

- 10. Let’s talk about few in detail
- 11. Docker ● Containers: ○ OS Virtualization ○ Process Isolation ○ Automation ○ Images ● Benefits of containers ○ Portable ○ Flexible ○ Fast ○ Efficient
- 12. Elastic Container Service ● Key Components: ○ Cluster: Group of container instance ○ Task Definition: Definition which define how to run tasks ○ Tasks: Unit of work ○ Service: Create service using tasks, automatically recover healthy container, help discover service ● It's a managed service ● Defined with custom schedulers ● Runs agent on all EC2 machines, help run cluster
- 13. Elastic Block Service ● Network block storage ● Designed for availability ● Attached to our EC2 instance ● Point in time snapshot ● Independent of EC2, so not fail even when EC2 instance fails ● Can be encrypted for security
- 14. Relational Database Service ● Fully managed relational database service ● Simple to deploy ● Easy to scale ● Automated backup ● DB snapshot ○ User driven database snapshot ● Easy to replicate ● Can have read replicas
- 15. OpsWorks ● Agent on each EC2 machine ● Understand commands triggered by Opswork and execute them ● Agent then runs a solo Chef run, Work with Chef ● Helps in ○ Automation ○ Scalability ○ Permissions ○ Resource management ○ Monitoring and lot more
- 16. OpsWorks ● Stack: Container of AWS resources ○ Region ○ Availability zones ○ Operating systems ● Layers: Blueprint that specify how to configure a set of EC2 machine ○ Load balancer ○ Web layer ○ Elastic IP ○ Security Group ○ Database Layer ● Instance: EC2 instance Gives ease of provisioning new environments/machines
- 17. Virtual Private Cloud ● Provide control of network architecture ● Help secure resources ● Predictable internal IP addresses ● Advances network access control ● Help provide isolated environment
- 18. IP Address Choose IP Address Range RFC1918 Subnet Setup subnet Internet Create route to internet Authorize Traffic to/from internet Provision Authorize Traffic
- 20. Server Configuration Solves problem to manually install and configure packages once hardware is ready. Chef is one which helps us setup all configuration Can deploy exactly same configuration machines. Opsworks has inbuilt support for chef.
- 21. Chef Server EC2 EC2 EC2 Chef client Pull recipes from server and run them Recipes help set up base configuration, giving proper permissions to users based on his roles, installing and running services and lot more.
- 22. Chef ● Provide framework to automate your infrastructure ● Ensures node complies with policy ● Policy is determined by configuration in each node’s run list ● Reduce management complexity through abstraction ● Policy states what state each resource to be in ○ Resource represent a piece of the system and things to be done: ■ Package to be installed ■ Service to be running ■ File should be generated ■ Users and groups to be managed etc ● Chef client pull all policies from Chef server
- 23. Deployment Deploy applications everyday and doing it manually can be real pain. Scripts saves our life here. Plan to move to Jenkins. Using ECR with ECS for deployment of services.
- 24. Collect Logs Crucial piece to tracking user operation and finding bugs easier. Make sure we track everything. Logentries is used which is a paid Saas service with free version.
- 25. Monitoring Crucial piece to manage and optimizing servers and databases. Make sure we track everything. New Relic is used which is a paid Saas service with free version. We track all action’s response time, db time and lot more matrix.
