Key Points

1. AWS services can come at 3 layers: iaas, paas, saas
2. Most references to AWS refer to paas - EC2 instances and the services that run on them
3. EC2 instances can be Windows or Linux
4. A low-cost iaas option is LightSail - a VPS server that is fixed price, low-cost with internet connectivity etc - easier to plan than EC2 costs
5. Effective cost management of AWS resources and services is a HUGE issue for most companies
6. EBS - elastic block storage - can be mounted and file system created for use. can be attached to any single instance

Compute Nodes

https://aws.amazon.com/ec2/pricing/?p=ps

Amazon EC2 is free to try. There are four ways to pay for Amazon EC2 instances: On-Demand, Reserved Instances, and Spot Instances. You can also pay for Dedicated Hosts which provide you with EC2 instance capacity on physical servers dedicated for your use.

Free Tier for 1 year

AWS Free Tier includes 750 hours of Linux and Windows t2.micro instances each month for one year. To stay within the Free Tier, use only EC2 Micro instances.

EBS - Elastic Block Storage devices

EBS volumes are highly available and reliable storage volumes that can be attached to any running instance that is in the same Availability Zone. EBS volumes that are attached to an EC2 instance are exposed as storage volumes that persist independently from the life of the instance. With Amazon EBS, you pay only for what you use. For more information about Amazon EBS pricing, see the Projecting Costs section of the Amazon Elastic Block Store page.

AWS Reserved Instances - RI

The most mature AWS customers are running more than 80% of their EC2 infrastructure covered by RI purchases. A best practice is to not let this number dip below 60% for maximum efficiency.

• Providing foundational education for engineering teams.
• Having visualization of cloud architecture, versus cost of those parts of the infrastructure.
• Facilitating robust tag enforcement, with easy ability to export cost and presentation to teams.
• Enabling reporting total spend, cloud spend, service management spend and contract spend, the entire cloud spend picture.
• Achieving container control, network and hardware integration at the scale and speed of cloud."
• Highlighting and fostering conversations around cloud cost management from a behavior change perspective

AWS services

AWS service levels - IAAS, PAAS, FAAS

Amazon Web Services (AWS) provides the infrastructure to host and run your applications at different levels of abstraction.The most obvious solution for hosting code is of course renting a bare metal machine, setting up the operating system andinstalling all necessary software. You can do that with Amazon EC2, although this service is more known for renting virtualmachines that run on physical hosts provided by Amazon. In both solutions you must care about the operating system you areusing and the installation of the server software (e.g. Tomcat).

Beanstalk - PAAS for Web apps

Amazon Beanstalk goes one step further by providing services that take a ready-to-use war file and deploy it on a virtual machinethat was setup by Amazon on behalf of you. As a developer you no longer have to care about the details of setting up the operatingsystem or the server software. If you implement your application such that it is independent of the OS and runs on the providedversion of Apache Tomcat, Amazon can automatically deploy your software and even scale out the number of virtual machinesnecessary to serve all clients without much delay. You just tell Amazon the limits it should operate in and you can concentrateon the implementation.

Serverless function concepts

Containers like Docker provide significant environment isolation and flexibility.

An app in a Docker container only talks to the Docker engine and the configured ports.

...

• locality of reference on data, libraries within a microservice to a high degree when caching is used
• environment agnostic
• easy to scale as a unit independent of other services in other containers

faas - single function deployed as a serverless service

the server is conceptually "invisible" to the developer

...

The most popular serverless platforms--AWS Lambda, Google Cloud Functions, Azure Functions--all present challenges once data gets involved. Want to talk to local AWS services? Dead simple. But once authenticated APIs get involved, it’s more of a pain. Where do you store tokens? How do you handle OAuth redirects? How do you manage users? Quickly that narrow use of serverless can snowball into a pile of other public cloud services … to the point that you’ve swapped the complexity developers know for some new piles of stuff to learn.

AWS Lamba Concepts

https://drive.google.com/open?id=153fxjcVnuov2wtJqoLfeSP55iY5rKQbZ

...

AWS Lambda was designed for use cases such as image or objects uploads to Amazon S3, updates to DynamoDB tables,responding to website clicks or reacting to sensor readings from an IoT connected device. AWS Lambda can also be used toautomatically provision back-end services triggered by custom HTTP requests, and "spin down" such services when not in use,to save resources

AWS Systems Manager Agent (SSM Agent) is Amazon software that can be installed and configured on an Amazon EC2 instance, an on-premises server, or a virtual machine (VM). SSM Agent makes it possible for Systems Manager to update, manage, and configure these resources. The agent processes requests from the Systems Manager service in the AWS Cloud, and then runs them as specified in the request. SSM Agent then sends status and execution information back to the Systems Manager service by using the Amazon Message Delivery Service (service prefix: ec2messages)With Amazon Lambda the level of abstraction is put even one step higher. With Lambda you no longer care about virtualmachines and their scale out yourself. All you have to do is to provide Amazon some code (typically in form of a prepared jarfile) and Amazon cares about its execution on behalf of you. In contrast to Amazon Beanstalk you . In contrast to Amazon Beanstalk you do not care about the numberof virtual machines used for the execution nor the number of load balancers. Amazon promises to execute your code as often as itis requested. And you pay only for the time used for its execution, not for the time your virtual machines are running.

POJO Object graphs

Your Java classes define your data model. With EclipseStore, there are no specific requirements to your classes. You can just use plain Java objects (POJOs). There is no need for specific superclasses, interfaces, annotations, mappings, or any other internal configurations.

• Use plain Java objects (POJOs)
• No superclass, interfaces, annotations
• No other internal configurations required
• All Java types supported
• Using inheritance is trouble-free

Storing Objects 
ACID Transaction-Safe

To persist objects in the storage, you just have to call a simple store method. By default, EclipseStore persists only new and changed objects (the delta). You decide explicitly, if and when objects are persisted. The objects are stored in a binary file appended to the file storage. Every store an atomic all-or- nothing blocking operation which is ACID transaction-safe and full consistent.

• Atomic all-or-nothing operation
• Blocking operation
• ACID transaction-safe
• Full consistency
• Append-log strategy
• Micro snapshot to store latest changes (delta)
• Rollback for operations on the object graph
• High IO speed through Eclipse Serializer
• Max IO speed by multithreaded IO ops 

query customers 

DataRoot root = EclipseStoreDemo.root();
root.getCustomers().add(customer);
EclipseStoreDemo.store(root.getCustomers());

CSV export / import

By using CSV Import/Export or other converters, any data can be migrated at any time in both directions easily.
