With Amazon Web Services (AWS), you can provision compute power, storage and other resources, gaining access to a suite of elastic IT infrastructure services as your business demands them. With minimal cost and effort, you can move your application to the AWS cloud and reduce capital expenses, minimize support and administrative costs, and retain the performance, security, and reliability requirements your business demands. This blog post discusses steps, techniques and methodologies for moving your existing enterprise applications to the AWS cloud
More and more enterprises are moving applications to the cloud to modernize their current IT asset base or to prepare for future needs. They are taking the plunge, picking up a few mission-critical applications to move to the cloud and quickly realizing that there are other applications that are also a good fit for the cloud. We discuss a phase-driven step-by-step strategy for migrating applications to the cloud.
Jenkins is an open source automation server. With Jenkins, organizations can accelerate the software development process through automation. Jenkins manages and controls development lifecycle processes of all kinds, including build, document, test, package, stage, deployment, static analysis and many more.
You can set up Jenkins to watch for any code changes in places like SVN and Git, automatically do a build with tools like Ant and Maven, initiate tests and then take actions like rolling back or rolling forward in production.
Set Up the Jenkins Server
Create an instance using the Amazon Linux AMI. Make sure you associate the instance with the CodeCommitRole role (Created in previous step) and configure the security group associated with the instance to allow incoming traffic on ports 22 (SSH) and 8080 (Jenkins). You may further secure your server by restricting access to only the IP addresses of local development environment connecting to Jenkins
While we build scalable, highly available and fault tolerant systems on Amazon Web Services, it is important to look out AWS deployment tools which can handle system and application level deployment ensuring consistency, predictability and integrity across multiple environments. This leads to continuous and faster deployment, lower failure and error rates and quick recovery.
Continuous Integration is a software development practice where continuous changes and updates in code base are integrated and verified by an automated build scripts using various tools.
Continuous Deployment is also a software development practice whose role is to automatically deploy the code to the specified server and application folder once the code is been integrated successfully.
Continuous Delivery is an end-to-end process for taking a functional requirement from concept to production as fast as is necessary to meet business needs. It depends on frequent deployments of small units of code rather than infrequent deployments of big releases. Successful continuous delivery also depends on DevOps—deep collaboration between development and operational IT functions
