AWS CloudFormation vs AWS OpsWorks: What are the differences?
What is AWS CloudFormation? Create and manage a collection of related AWS resources. You can use AWS CloudFormation’s sample templates or create your own templates to describe the AWS resources, and any associated dependencies or runtime parameters, required to run your application. You don’t need to figure out the order in which AWS services need to be provisioned or the subtleties of how to make those dependencies work.
What is AWS OpsWorks? Model and manage your entire application from load balancers to databases using Chef. Start from templates for common technologies like Ruby, Node.JS, PHP, and Java, or build your own using Chef recipes to install software packages and perform any task that you can script. AWS OpsWorks can scale your application using automatic load-based or time-based scaling and maintain the health of your application by detecting failed instances and replacing them. You have full control of deployments and automation of each component .
AWS CloudFormation and AWS OpsWorks are primarily classified as "Infrastructure Build" and "Server Configuration and Automation" tools respectively.
Some of the features offered by AWS CloudFormation are:
- AWS CloudFormation comes with the following ready-to-run sample templates: WordPress (blog),Tracks (project tracking), Gollum (wiki used by GitHub), Drupal (content management), Joomla (content management), Insoshi (social apps), Redmine (project mgmt)
- No Need to Reinvent the Wheel – A template can be used repeatedly to create identical copies of the same stack (or to use as a foundation to start a new stack)
- Transparent and Open – Templates are simple JSON formatted text files that can be placed under your normal source control mechanisms, stored in private or public locations such as Amazon S3 and exchanged via email.
On the other hand, AWS OpsWorks provides the following key features:
- AWS OpsWorks lets you model the different components of your application as layers in a stack, and maps your logical architecture to a physical architecture. You can see all resources associated with your application, and their status, in one place.
- AWS OpsWorks provides an event-driven configuration system with rich deployment tools that allow you to efficiently manage your applications over their lifetime, including support for customizable deployments, rollback, partial deployments, patch management, automatic instance scaling, and auto healing.
- AWS OpsWorks lets you define template configurations for your entire environment in a format that you can maintain and version just like your application source code.
"Automates infrastructure deployments" is the primary reason why developers consider AWS CloudFormation over the competitors, whereas "Devops" was stated as the key factor in picking AWS OpsWorks.
According to the StackShare community, AWS CloudFormation has a broader approval, being mentioned in 195 company stacks & 75 developers stacks; compared to AWS OpsWorks, which is listed in 73 company stacks and 18 developer stacks.
