Amazon S3 is an object storage service that offers industry-leading scalability, data
availability, security, and performance. You can use Amazon S3 to store and retrieve any
amount of data at any time, from anywhere.
Amazon S3 Glacier is a secure and durable service for low-cost data archiving and
long-term backup. With S3 Glacier, you can store your data cost effectively for months,
years, or even decades.
AWS EBS is an easy-to-use, scalable, high-performance block-storage service
designed for Amazon EC2 instance. Assume it like an portable Hard Drive which can
attach or detach to/from any Server anytime.
Amazon EFS is a simple, serverless, set-and-forget, elastic file system. Applications
that require shared file access can use Amazon EFS for high aggregate throughput
to thousands of clients simultaneously.

26. Some Cloud Services > Database Services
AWS Database Services is a set of databases offered by AWS on the cloud. Provides a wide range of fully
managed, purpose-built and both relational and non-relational database services specially designed to handle
any kind of application requirements.
RDS
Relational Database
Service
Dynamo DB
Non Relational
Database Service
Amazon RDS is a service that supports various open-source relational database
products including the database products provided by AWS itself. RDS is used to set up,
operate, and scale a relational database in the cloud. It automates administrative tasks
such as hardware provisioning, database setup, backups, and more.
Features: Performance at scale, Replication via Multi AZ deployment, Read Replicas, Auto
Backup and Restore and Auto upgrade.
Amazon DynamoDB is a fast, fully managed, and flexible NoSQL database. It also
supports document-based data. AWS affirms that DynamoDB delivers single-digit
millisecond performance at any scale. DynamoDB comes with built-in Security, Backup,
and Restore features. Since DynamoDB is a NoSQL database, it doesn’t require any
schema.

27. Some Cloud Services > Networking
Similar to traditional on-premises networking, cloud networking provides the ability to build, manage, operate,
and securely connect your networks across all your cloud environments and distributed cloud and edge
locations.
VPC
Foundation
API Gateway
Application N/W
AWS VPC (Virtual Private Cloud) is the your private cloud in AWS were you create the
resources and manage them. Every resource you create is belongs to a specific VPC.
Example you create a server (EC2) and attach it to your VPC. VPC have an address
range which further allocated to the Subnets and then to the resources.
AWS API Gateway is an AWS service for creating, publishing, maintaining, monitoring,
and securing REST, HTTP, and WebSocket APIs at any scale. APIs act as the "front door" for
applications to access data, business logic, or functionality from your backend services.
API Gateway handles all the tasks involved in accepting and processing up to hundreds
of thousands of concurrent API calls.
CloudFront
Edge networking
AWS CloudFront is a web service that speeds up distribution of your static and dynamic
web content, such as .html, .css, .js, and image files, to your users. CloudFront delivers
your content through a worldwide network of data centers called edge locations. This is
an AWS Content Delivery Network (CDN).

28. Some Cloud Services > Networking
Similar to traditional on-premises networking, cloud networking provides the ability to build, manage, operate,
and securely connect your networks across all your cloud environments and distributed cloud and edge
locations.
Route 53
Edge networking
VPN
Hybrid connectivity
AWS Route 53 is a highly available and scalable Domain Name System (DNS) web
service. Route 53 connects user requests to internet applications running on AWS or on-
premises. There are many usage of Route 53 like Manage network traffic globally, Build
highly available applications, Set up private DNS etc.
AWS Client VPN - used by your remote workforce to securely access resources both on
AWS and within your on-premises networks.
AWS Site-to-Site VPN - AWS Site-to-Site VPN creates encrypted connections between
your locations (such as data centers and remote offices) and your AWS resources.
Direct Connect
Hybrid connectivity
AWS Direct Connect cloud service is the shortest path to your AWS resources. While in
transit, your network traffic remains on the AWS global network and never touches the
public internet. We use this service when we need high speed, secure and large dataset
to transfer or extending our existing network (Hybrid).

29. Some Cloud Services > Networking
Similar to traditional on-premises networking, cloud networking provides the ability to build, manage, operate,
and securely connect your networks across all your cloud environments and distributed cloud and edge
locations.
WAF
Network Security
Firewall
Network Security
AWS WAF is a web application firewall that helps protect web applications from attacks
by allowing you to configure rules that allow, block, or monitor (count) web requests
based on conditions that you define such as IP addresses, HTTP headers and body, or
custom URIs.
AWS Network Firewall used to create firewall rules that provide fine-grained control over
network traffic and easily deploy firewall security across your VPCs. You can use Firewall
in the cases like Inspect VPC-to-VPC traffic, Filter outbound traffic, Secure AWS Direct
Connect and VPN traffic, Prevent inbound internet traffic intrusion etc.
