A company wants to migrate its on-premises application to AWS. The application produces output files that vary in size from tens of gigabytes to hundreds of terabytes. The application data must be stored in a standard file system structure. The company wants a solution that scales automatically. is highly available, and requires minimum operational overhead.
Which solution will meet these requirements?
A. Migrate the application to run as containers on Amazon Elastic Container Service (Amazon ECS). Use Amazon S3 for storage.
B. Migrate the application to run as containers on Amazon Elastic Kubernetes Service (Amazon EKS). Use Amazon Elastic Block Store (Amazon EBS) for storage.
C. Migrate the application to Amazon EC2 instances in a Multi-AZ Auto Scaling group. Use Amazon Elastic File System (Amazon EFS) for storage.
D. Migrate the application to Amazon EC2 instances in a Multi-AZ Auto Scaling group. Use Amazon Elastic Block Store (Amazon EBS) for storage.
Option C- Migrate the application to amazon ec2 instances in a multi-AZ auto scaling group. Use amazon EFS for storage.
Because efs provides standard file system structure, Automatic scaling, High availability across multiple AZs.
A company needs to store its accounting records in Amazon S3. The records must be immediately accessible for 1 year and then must be archived for an additional 9 years. No one at the company, including administrative users and root users, can be able to delete the records during the entire 10-year period. The records must be stored with maximum resiliency.
Which solution will meet these requirements?
Use amazon s3 with object lock in compliance mode, enable versioning & set a 10-year retention period.
Store data in s3 standard for 1 year, then use a lifecycle rule to move it to s3 glacier deep archive for the remaining 9 years. This ensures max resiliency & prevents deletion by any user.
What is 2-tier architecture and what are its advantages?
2-tier architecture is a type of client-server architecture where the application is divided into two layers (tiers):
Client Tier (Presentation Layer):
This is the user interface, typically an application or a browser running on a user's device.
Server Tier (Data Layer):
This handles the database and data access logic.
The server directly communicates with the database.
