The document outlines a presentation on cloud computing with AWS, delivered by Kalema Edgar, a seasoned technology manager and AWS certified expert. It covers key topics such as cloud strategy, migration challenges, AWS services, and preparing for the AWS Cloud Practitioner exam. Additionally, it emphasizes the importance of a strong cloud strategy and provides practical homework for attendees to reinforce their learning.
![Cloud Strategy
Over 37% of cloud migrations fail. Brands like Twitter,
Pinterest and TSB, a UK based bank experienced failure
during their cloud migration implementation.
Key reason for failure was:
Not having a strong and clear cloud strategy before embarking on
the migration journey. [according to the CSA report]
“Good tactics can save even the worst strategy. Bad tactics will destroy even the best strategy.”
General George S. Patton Jr.

- 24. Common AWS Services ● Elastic Compute Cloud (EC2) ● Elastic Block Store (EBS) ● AWS Auto Scaling ● Elastic Load Balancing (ELB) ● Amazon Virtual Private Cloud (VPC) ● Amazon Identity and Access Management (IAM) ● Amazon Simple Storage Service (S3) ● Amazon DynamoDB ● Amazon API Gateway ● Route 53 ● Elastic Beanstalk ● AWS Lambda
- 25. Elastic Compute Cloud (EC2) ● Provides secure, resizable compute capacity ● Let’s you run virtual servers in the cloud ● Only pay for running instances (not terminated instances) ● Reliable, scalable, infrastructure on demand ● Multi-tenancy model
- 26. EC2 Billing / Pricing Options https://cdn.ttgtmedia.com/
- 27. Elastic Block Store (EBS) ● Relate to hard drives (like external hard-drives) ● Persistent block storage for use with EC2 instances. You need to attach them ● Store important data here and ensure these are backed up. ● Automatically replicated within it’s AZ to protect from component failure. ● You can create point in time snapshots and restore the instance to that point in time. amazon.com
- 28. Amazon EC2 Auto Scaling ● Achieve scalability and elasticity ● Increase application availability ● Pay for only the resources you use. ● Automatically add or remove instances (demand / predictive). ● Improve fault tolerance - detect, terminate and replace faulty instance Images from aws.skillbuilder.com

- 33. Elastic Beanstalk ● Service for deploying and scaling web apps and services. ● Supports Java, .NET, PHP, Node.js, Python, Ruby, Go, Docker ● Supports Apache, Nginx, Passenger, and IIS web servers ● Simply upload your code (zip) and Beanstalk handles: ○ Deployment ○ Capacity provisioning ○ Load Balancing ○ Monitoring ● And you retain control over the created resources.
