Key Points
- AWS services can come at 3 layers: iaas, paas, saas
- Most references to AWS refer to paas - EC2 instances and the services that run on them
- EC2 instances can be Windows or Linux
- 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
- Effective cost management of AWS resources and services is a HUGE issue for most companies
- EBS - elastic block storage - can be mounted and file system created for use. can be attached to any single instance

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).

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.

create an admin user acct
If you don't already have an access key for your AWS account root user, don't create one unless you absolutely need to. Instead, use your account email address and password to sign in to the AWS Management Console and create an IAM user for yourself that has administrative permissions.
