Define the AWS Cloud and its value proposition

AWS -Amazon Web Services

AWS Cloud is a robust Cloud Services Platform offering various of services to customers.
What is cloud computing?

Simply put, AWS is a Cloud Platform with robust security offering services like:-

  • Compute
  • Migration
  • Database
  • Storage
  • Networking
  • Analytics
  • Security
  • Servers
  • Development

Before moving on to developments in AWS, let dig into some basics of Cloud Computing.

What is Cloud Computing?

Cloud Computing:-

  • Offers all resources need to operate a Computation Environment (Servers, Databases etc.)
  • Pay for the cloud services that you use               
  • Reduce your running costs
  • Operate your network more effectively and scale up as you buy.
  • Have limited Control over the resources.

Benefits and considerations of using cloud services:-

Availability1.Model based on pay-as-you-go / consumption

2.You should quit paying the money you don’t need

3.Cost Prediction to plan
Scalability1.  You have infinite resources

2.Scaling vertically (scaling up) –can add more CPU Power

3.Scaling horizontally (scaling out)-You can add more power by installing additional servers

4.Automatic or manual scaling
Elasticity1. Increase or decrease according to request

2. Peak Season’s- Install –> +servers

3. low seasons-Reduce–>-servers

4.Compliant with sudden spikes

5. Minimise low-use consumption
Agility1. Fast systems with full power

2.Can add power–>As per requirement
Fault-Tolerance1.  Data centres redundant

2.  Fault-tolerant infrastructure

3.  Policy and controls developed

4.  Security Model–>Shared
Disaster Recovery1.  Backup and duplication of data

2.  Recovery –>Generators (In case of Sever Problems)

Different Types of Cloud Computing Models

Infrastructure-as-a-Service (IaaS)

Compute, Networking & Storage Services are offered in this service model.

Infrastructure as a Service –>Provides most versatile type of cloud provisioning.

This model offers a renting model of the infrastructure with less start-up costs along with full-control over operating systems, virtual machines, data &Application

Platform-as-a-Service (PaaS)

This model supports everything expect your data & Applications.

Ex:- A web Application–>The cloud vendor provides all the necessary infrastructure ranging from servers to operating systems and provides a platform for application deployment.

Software-as-a-Service (SaaS)

Simply put, the software is provided by the cloud-vendor and end users make use of the applications.

Ex: – Salesforce CRM, Office 365 etc.

Compare and contrast the three different service types

Different Types of Cloud Computing Models

Describe the differences between Public, Private and Hybrid cloud models:-

Public cloud

Your data/application runs on cloud vendor-managed infrastructure, such as Azure etc.

Private cloud

Your data /applications run locally at your own premises and manage the data centre on own.

Hybrid cloud

Some of your data /application run on-site while other part runs on a cloud vendor-managed infrastructure.

Compare and contrast the three different cloud models

TypesAdvantagesDisadvantages
PublicScalability–>High Strength/mobility
Pricing–>Pay As U Go
Infrastructure–>No Maintenance
Technical Skill–>Less
Security Standards(some)–>Cant meet
Compliance Standards–>some Cant meet
Infrastructure–>Less
PrivateData Centre–>Full Control
Standards–>Full Compliance &Legal
Initial Costs–>High
Flexibility–>Less
HybridEconomy–>Save costs by mixing both
Public+private
Flexibility–>High
Management & Setup–>Complex
Costs–>High
Maintenance–>High

Identify aspects of AWS Cloud economics

AWS Cloud Economics helps to reduce the overall costs of managing the virtual environments.

It allows the customer to have full control over the operating costs.

The AWS TCO(Total cost ownership) is used to help the customers make informed decisions.

What is TCO ( Total Cost Ownership)?

The Total cost ownership is the comparative analysis between the on-premise environment & cloud environment in terms of costs.

List the different cloud architecture design principles

There are various 5 Pillars in the Cloud Architecture:

The frameworks enabled the cloud architecture to be robust and secure environment.

1. Operational Excellence

The 5 design Principles are:

  • Perform operations as code
  • Anticipate failure
  • Learn from all operational failures

2. Security

  • Automate security best practices
  • Protect data in transit and at rest
  • Keep people away from data

3. Performance Efficiency

  • Democratize advanced technologies
  • Go global in minutes
  • Use serverless architectures

4. Cost Optimization

  • Adopt a consumption model
  • Measure overall efficiency
  • Stop spending money on undifferentiated heavy lifting

5. Reliability

  • Automatically recover from failure
  • Test recovery procedures
  • Scale horizontally to increase aggregate workload availability

Domain 2: Security and Compliance 25%


Define the AWS shared responsibility model

Simply put, Shared responsibility model defines the terms what AWS and Customer is responsible for.

AWSResponsible of the cloud environment
CustomerResponsible inside the cloud environment

Define AWS Cloud security and compliance concepts

AWS Security

AWS gives security-explicit devices and highlights across network security, configuration management, access control, and information encryption.

This implies you hold control of the security

Security in the cloud is a lot of like security in your on-premises server farms—just without the expenses of keeping up offices and equipment.

You gain admittance to several devices and highlights to assist you with meeting your security Standards.

AWS Compliance

AWS Infrastructure is accredited to

SOC 1/ISAE 3402, SOC 2, SOC 3

FISMA, DIACAP, and FedRAMP

PCI DSS Level 1

ISO 9001, ISO 27001, ISO 27017, ISO 27018ISO 27001, SOC2. SOC3.

IAM service comes under security & compliance section

To use IAM service Management console

IAM SERVICES

IAM Best practices

Root Account—> Default

# Users belong to an organisation can be grouped

EX: Group 1 – Admin & Group 2- Developers

Groups cant contain other groups

Permissions & Policies are created while creating users and groups to maintain best security practises.

This structure typically works well in a decentralised IT environment where each BU is responsible for its own IT administration, operations, and costs.

Environment Life cycle Account Structure

Allows customers to align their AWS operational and billing controls with their application deployment life cycle.

Project-Based Account Structure

Allows customers to align their AWS operational and billing controls by product, application workload, or program.
