AWS Core services: * The AWS web console: the entry point for configuring your infrastructure in the AWS cloud * The Free Tier and how to setup billing alerts * Elastic Compute Cloud (EC2) instances, and the ease with which you can pick a particular Amazon Machine Image (AMI) for your workload, and spin it up as an instance right away * How to create and deploy a high-availability web application in AWS, with an Elastic Load Balancer (ELB) and a multi-availability-zone Relational-Database-Service (RDS) instance * How CloudFormation can automate all of the above​. Serverless Functions: Serverless architecture allows developers to focus on code and their business problem rather than spending time looking after backend infrastructure. Serverless architecture can help developers build scalable, high-performing, and cost-effective applications quickly We will talk about how serverless architecture and AWS Lambda can make things easier, cheaper, and help to accelerate development of projects.

• Sign up through https://aws.amazon.com
• You will need a credit card
• There will be a telephone verification
• Choose a zone
• try and stick to one
• Ireland is Best!

14. Simple Storage Service (S3)
• Cloud based file storage
• Simple API to CRUD files
• Unlimited capacity
• Static website hosting

16. EC2
• Hardware virtualization in the cloud
• Various sized servers
• All major operating systems
• Provision, configure, start and stop machines
from your App!
• Full operating system access via SSH and
Security Groups

18. Elastic Beanstalk
• Deploy and scale web applications
• Languages: Java, .NET, PHP, Node.js, Python, Ruby…
• Servers: Apache, Nginx, Tomcat , IIS
• Upload your code; AWS handles:
Deployment
Capacity Provisioning
Load balancing
Auto scaling
Health Monitoring

19. Elastic Beanstalk

21. EC2 Container Service
• Run Docker containers in EC2 cluster
• API controlled
• Support Images from private Docker
repositories
• Docker CE and EE for AWS
• Docker swarm for Cloud

23. Tooling
• AWS and EB CLI
• IDE integration – Eclipse, IntelliJ,
Visual Studio
• AWS SDK
• API to manage AWS services
• Use services from within your
application
• Android and IOS app

25. Billing
Free Tier
• Free for 12 months
• EC2 - run 1 micro instance x 1 month or 2
micro instances x half a month
• S3 - 5 GB of Standard Storage
• First 1 million Lambda calls a month
And a lot more….

27. SSH
• SSH keys are used for secured
access to EC2 instances

34. AWS Lambda is a compute
service that runs your code in
response to events and
automatically manages the
compute resources for you

35. Run code in response to events

37. LAMBDA PRICING
• Lambda
– Requests
• First 1 million per month are free
• $0.20 per 1 million requests thereafter
– Duration
• Charged per 100ms execution time
• First 400,000 GB-seconds of compute time per month are free
• $0.00001667 for every GB-second thereafter
• API Gateway
– $3.50 per million API calls received plus data transfer
costs
• Estimate for Malicious Domain Application:
• Lambda: $0.37/hour with 10 threads after free-tier
• API Gateway: $0.71/hour
• Total: ~$1/hr

39. Lambda Considerations
• Lambda can be invoked by **anything** or you can
figure out a way to make it happen.
• NodeJS performs well
• Stateless
• Cold start behavior

42. Available in the US, UK, Germany,
Japan and India

43. • Register a device
• Link third-party accounts (Twitter)
• View lists
• Call and Message
• Home Automation
• And much more
