Cloud Foundation Concepts

Question 1

What are the characteristics of Availability Zones?

Answer 1

1. Physically separted
2. Connected through a low-latency links
3. Fault tolerant
4. Allows for high availability

Question 2

What is an AWS Region?

Answer 2

• It’s a physical location where AWS has data centres.
• A region contains multi Availibility Zones

Question 3

What are the AWS Region Characteristics?

Answer 3

1. Fully independent and Isolated (from other regions)
2. Resource and Service Specific

Question 4

What are AWS Availability zones?

Answer 4

Availability zones consists of one or more separated data centres, each with redundant power, networking and connectivity, housed in separate facilities.

e.g. Region: N.Virginia

Availability Zones:

1. US-EAST-1A
2. US-EAST-1B
3. US-EAST-1C
4. US-EAST-1D
5. US-EAST-1E
6. US-EAST-1F

Question 5

What are Edge Locations?

Answer 5

Edge locations cache content to fast delivery to your users. It’s made possible through AWS CloudFront. It’s recudes latency (Low Latency is good).

NB: Latency: Is the time that passes between a user request and resulting response.

Question 6

What is AWS Management Console?

Answer 6

AWS Management console allows users to access AWS account and manage applications running in the account from a web broswer.

• Networking - e.g. VPC, AWS Direct Connect
• Storage - e.g. S3 (Simple Storage Service),EBS(Elastic Block Service)
• Analytics - e.g Athen, Redshift
• Development - e.g Cloud 9 , Code Commit
• Security - e.g. IAM , Amazon Macie
• Database - e.g RDS, DynamoDB

Question 9

What are the 4 Benefits of Cloud computing?

Answer 9

1. High Availability - Low failure rate
2. Elasticity - Scale environment easily (Shrink and Grow) as when required
3. Agility - Innovate faster through leveraging existing services
4. Durability - Long-term data storage protection.

Question 10

Define 3 Cloud deployment models?

Answer 10

1. Private cloud (on premises datacenter)
2. Public Cloud (AWS, AZURE - benefit from Economics of Scale)
3. Hybrid Cloud (Combination of Public and Private) e.g. Through the use of AWS Direct Connect

Question 11

Name 6 advantages of Cloud computing?

Answer 11

1. Increase speed and agility
2. Trading capital expense for operational expense
3. Stop guessing capacity
4. Benefit from massive economies of scales
5. Focus on your developing your applications vs managing hardware
6. Scale easily

Question 12
