[Q/A] AWS Certified Solution Architect Associate Day 1: Introduction To Cloud & AWS

[Q/A] Related to Cloud Services and Deployment Model

Below are a few questions asked by Trainee, related to this topic

Q1. What are the 3 types of cloud services?
Ans. There are three main service models of cloud computing:

Infrastructure as a Service (IaaS)
Platform as a Service (PaaS)
Software as a Service (SaaS).

Q2. Give some examples of IAAS, PAAS, SAAS.
Ans. Examples Of IAAS, PAAS, SAAS are:

IAAS: DigitalOcean, Rackspace, Amazon Web Services (AWS), Cisco Metapod, Microsoft Azure, Google Compute Engine
PAAS: AWS Elastic Beanstalk, Heroku, Windows Azure, Force.com, OpenShift, Apache Stratos.
SAAS: Google Apps, Salesforce, Dropbox, MailChimp, ZenDesk, DocuSign, Slack, Hubspot.

Q3. What is SAAS in AWS?
Ans. Software-as-a-Service (SaaS) SaaS products are deployed, managed, and sold by ISVs and hosted by a cloud provider such as AWS. Instead of installing and maintaining software, you simply access it via the Internet, freeing yourself from complex software and hardware management.

Q4. What is a hybrid cloud platform?
Ans. A hybrid cloud comprises both public and private clouds. It has shared security responsibility. Hybrid Cloud helps maintain tighter controls over sensitive data and processes.

[Q/A] Related to AWS Global Infrastructure Region AZ

Q5. What is AWS infrastructure?
Ans. The AWS Global Cloud Infrastructure is the most secure, broad, and dependable cloud stage, offering more than 175 fully-featured services from the data centers globally. With millions of active customers and tens of thousands of partners globally, AWS has the biggest and most powerful biological system.

Q6. What is the difference between the AWS Region and Availability Zone?
Ans. AWS Cloud computing resources are housed in highly available data center facilities. AWS Regions are huge and generally scattered into independent geographic areas. Availability Zones are distinct locations within an AWS Region that are designed to be isolated from failures in other Availability Zones.

Q7. What is the main difference between an availability zone and an edge location?
Ans. Availability zones are a bunch of data centers that host all your resources. Edge locations are the small data centers that host static & dynamic web contents.

Q8. What is the use of edge computing?
Ans. Edge computing helps decentralize data processing and lower reliance on the cloud. Edge computing has several benefits, such as Increased data security and privacy. Better, more responsive, and powerful application performance.

[Q/A] Related to AWS Services

Q9. What is AWS Services?
Ans. AWS Services are:

Deployment & Management
Application Services
Foundation Services

Q10. What is an IAM role?
Ans. An IAM role is an IAM entity that defines a set of permissions for making AWS service requests. IAM roles are not related to a particular user or group.

Q11. What is the difference between roles and groups?
Ans. A group is a collection of users with a given set of permissions assigned to the group. A role is a collection of permissions, and a user effectively inherits those permissions when he acts under that role.

Q12. What is AWS MFA?
Ans. AWS multi-factor authentication (AWS MFA) provides an additional level of security that you can apply to your AWS environment. You can enable AWS MFA for your AWS account and for individual AWS IAM users you create under your account.

Q13. What is AWS Lambda?
Ans. AWS Lambda is a serverless compute service and lets users run code without managing servers. User pays only for the compute time they consume – there is no charge when your code isn’t running. With Lambda, user can run code for virtually any type of application or backend service.

[Q/A] Related to Storage Services

Q14. How many types of storage are there in AWS?
Ans. There are three types of cloud data storage:

Object Storage
File Storage
Block Storage

Q16. What can I do with Amazon S3?
Ans. Amazon S3 provides a simple web service interface that you can use to store and retrieve any amount of data, at any point in time, from anywhere on the web. By using the S3 service, you can easily build applications that make use of Internet storage. Amazon S3 is a highly scalable service and you only pay for what you use.

[Q/A] Related to Network Service

Q17. What is Amazon route 53?
Ans. Amazon Route 53 is a highly efficient and scalable cloud web service and is also used for health checking of resources. It provides developers with an efficient and reliable way to connect users to internet applications without any delay, it still has a delay in servers or applications, but users may not be aware of it. It effectively connects user requests to AWS such as Amazon EC2 instances, Elastic Load Balancing, or Amazon S3 buckets.

Q18. Why should I use Amazon VPC?
Ans. Amazon VPC enables users to build a virtual network in the AWS cloud without VPN, hardware, or physical datacenters required. User can define their own network space, and control how their network and the Amazon EC2 resources inside their network are exposed to the Internet. Users can also leverage the enhanced security options in Amazon VPC to provide more granular access to and from the Amazon EC2 instances in your virtual network.

Q19. What is cloud front in AWS?
Ans. Amazon CloudFront is a fast content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to customers globally with low latency, high transfer speeds, all within a developer-friendly environment.

Q20. What is latency in cloud computing?
Ans. Cloud service latency is the delay between a client request and a cloud service provider’s response.

[Q/A] Related to Database Services

Q21. What is DynamoDB Accelerator in AWS?
Ans. Amazon DynamoDB Accelerator (DAX) is a fully managed, highly available, in-memory cache for Amazon DynamoDB that delivers up to a 10 times performance improvement—from milliseconds to microseconds—even at millions of requests per second.

[Q/A] Related to Application Services

Q23. How is Amazon SQS different from Amazon SNS?
Ans. Amazon SNS permits applications to send time-critical messages to multiple subscribers through a “push” mechanism, eliminating the need to periodically check or “poll” for updates. Amazon SQS is a message queue service utilized by distributed applications to exchange messages through a polling model and can be utilized to decouple sending and receiving components.

Q24. What are the benefits of using Amazon SNS?
Ans. Benefits of Amazon SNS are:

Quick, push-based delivery
Simple APIs and easy integration with applications
Flexible message delivery over multiple transport protocols
Reasonable, pay-as-you-go model with no up-front costs
Web-based AWS Management Console offers the simple point-and-click interface

[Q/A] Related to Audit and Monitoring

Q25. What types of monitoring services does CloudWatch provide?
Ans. CloudWatch provides two types of monitoring services:-

Basic Monitoring: – It is a free service that includes polls every 5 minutes, 10 metrics, 5GB of data ingestion, 5Gb of data storage.
Detailed Monitoring: – It is a chargeable service that includes polls every minute and is charged per instance per month.

Q26. Who should use CloudTrail?
Ans. Customers who need to track changes to resources, answer simple questions about user activity, demonstrate compliance, troubleshoot, or perform security analysis should use CloudTrail.

Q27. How is CloudFormation different from AWS Elastic Beanstalk?
Ans. These services are designed to complement each other. AWS Elastic Beanstalk provides an environment where you can easily deploy and run applications in the cloud. It is integrated with developer tools and provides a one-stop experience for managing the application lifecycle. If your application workloads can be managed as Elastic Beanstalk workloads, you can enjoy a more turn-key experience in creating and updating applications. Behind the scenes, Elastic Beanstalk uses CloudFormation to create and maintain resources. If your application requirements dictate more custom control, the additional functionality of CloudFormation gives you more options to control your workloads.

AWS CloudFormation is a convenient provisioning mechanism for a broad range of AWS and third-party resources. It supports the infrastructure needs of many different types of applications such as existing enterprise applications, legacy applications, applications built using a variety of AWS resources, and container-based solutions.
