AWS Training Oct 2015 – Mar 2016
Attended Amazon Web Services training that covered the following modules:
EC2, EBS, S3, RDS, ELB, SQS, SES, SWF, Glacier, RRS, RedShift, DynamoDB, Import/Export Snowball, Storage Gateway, ElastiCache, Elastic BeanStalk, Elastic File System, Security Groups, Route 53, Auto Scaling, VPC, VPC Peering, Kinesis, Aurora, Direct Connect, IAM, CloudFront, Chef, Git, WordPress, and Workspaces.
Solutions were designed and developed as part of three training projects that engaged all the services of AWS that were covered, one for building a highly scalable architecture for a large website and the other for a blogging platform using WordPress. Also, one of the projects for the training had to do with automation using Chef.
Designed and developed a solution for building a highly scalable architecture for a large website.
The project had the following specific requirements:
•The site should be highly available, provide fast response time to users and support several thousand simultaneous users. The application has to be load-balanced between several instances spread across multiple availability zones.
•The site should not have any single point of failures (SPOFs). It should allow an availability Zone or instances to be taken offline for updates, patches and testing new software versions without impacting traffic flow.
•The application has to split read/write database traffic – writes must go to master DB, and the slaves should perform reads. There should be enough read databases to handle at least 80% read-traffic that is expected. The database requires high performance from its disks and has to support at 1000 IOPs.
•The application requires a database caching layer – the current application uses MemCached cache layer for improved performance. The requirement is to continue using MemCached.
•Ensure media objects (images, videos) and large files like PDFs are NOT delivered by the web servers.
•Use CDNs to alleviate load on the web servers.
•Each instance requires 10GB of disk space to store data files. The instance needs to be running the latest Ubuntu software and needs to have Java JDK 7, Apache2, PHP5 and Memcached client installed. The instances should have a minimum of 7GB memory (RAM) available.
•Static website hosting is required as a fallback to the website.
•The client has several CSV files that contain their data. They are named customers, orders, vendors, inventory and so on. Research the best way that can be used to import these CSV files into the database tables.
•The client wants to maintain 30 days of database backups and the backup window needs to be between 12am – 1am ET because that’s the least busy window for their application.
•Once all the data is loaded from the CSV files, the clients wants to create a standalone database from the existing master database. The standalone database will be used for report generation and analysis without impacting the real database servers.
