Running WordPress site in the cloud across multiple instances can create a never-ending list of challenges in order to keep your site running optimally. Administration of unpredictable code updates or theme changes can create a never-ending litany of manual or programmatic updates to every single Amazon EC2 instance hosting WordPress. Come join us in this deep dive session, where we detail how you can leverage EC2, Amazon RDS, Amazon ElastiCache, Auto Scaling, Elastic Load Balancing, Amazon Route 53, and Amazon CloudFront. We explore how to take advantage of Amazon Elastic File System (Amazon EFS) and Amazon Simple Storage Service (Amazon S3) as shared storage to deliver a highly available and massively scalable infrastructure that can dynamically scale up or down to automatically adjust to unpredictable traffic demands. We also share best practices, provide performance tuning hints, and describe cost optimization techniques throughout.
