(web302) best practices for running wordpress on aws | aws re:invent 2014
DESCRIPTION
WordPress is an open-source blogging tool and content management system (CMS) that can power anything from personal blogs to high traffic websites. This session covers best practices for deploying scalable Wordpress-powered websites on AWS. Starting from one-click single-instance installations from the AWS Marketplace, we move on to Wordpress implementation details that help you make the most of AWS elasticity. We provide a blueprint architecture for high availability (Elastic Load Balancing, Auto Scaling, Amazon RDS multi-AZ). You learn how to use Amazon S3 to create a stateless web tier, how to improve performance with Amazon ElastiCache and Amazon CloudFront, how to manage your application lifecycle with AWS Elastic Beanstalk, and more.TRANSCRIPT
