Cloud computing provides on-demand access to computing resources like servers and storage that can be provisioned quickly. While traditional data centers provide more control, cloud infrastructure offers more flexibility and a pay-as-you-go model. Setting up a simple WordPress blog on AWS' free tier is a good way to learn cloud basics and try services like EC2, RDS, S3, and CloudFront.

AWS 101 Guide
- 1. Cloud 101 Amazon Web Services Getting Started
- 2. A Simple Definition At a basic level Cloud Computing is a collection of: • Compute • Storage • Networking Resources that can be consumed on demand.
- 3. Cloud vs Traditional DC Cloud Advantages • Flexible Infrastructure – Quick to provision • “On demand” servers – Power on/off as you need • Pay as you go service – Public cloud only Disadvantages • Lack of physical access Traditional Data Centres Advantages • Complete Control Disadvantages • Wasted Resources • Long lead times for new equipment • Always on Infrastructure
- 4. Problems in a Traditional DC • You need to plan capacity carefully • Often an unknown quantity • Best guess • Finite resource • Limited ability to burst • Wasted resource

- 12. Billing Alerts Even if you are careful sometimes you can incur charges, so its best to set up a billing alert as your first task. • Billing alerts will email you if you exceed a certain value • You can even alert if you go $0.01 over the free tier usage • It’s a simple 9 step process found here: • http://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/create-billing-alarm.html
- 13. What to build? The free tier is good for simple, low to moderate usage websites Perfect to try a WordPress Blog with the following components: • EC2 Linux Server (running apache) • I recommend Amazon Linux as a a t2.micro • RDS MySQL Database • Choose the none multi-AZ deployment and db.t2.micro • Elastic Load Balancer (not needed as only one server but good to learn) • S3 Storage (For storing files uploaded to WordPress) • CloudFront (Optional but good for taking pressure off the server) • SES (for sending emails to users) • Identity controls • IAM for user access Guide: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/hosting-wordpress.html
- 14. Taking WordPress Further The previous guide only goes so far, so have a play and add in the extra services. Try using RDS instead of installing MySQL. You’ll get a better performing website. You should end up with something like this:
- 15. Taking WordPress Further These building blocks aren’t that different to a full scale deployment to run very large sites. There are just more parts. You’ve now got all the skills to do this.
