What are some of the key features of the VPC model?
Some key features of the VPC model are:
- Agility - Ability to control the size of your virtual network and deploy cloud resources dynamically as needed.
- Availability - Redundant resources and highly fault-tolerant availability zone architectures provide high availability.
- Security - Logical isolation from other public cloud tenants provides security and control over resource access.
- Affordability - Ability to take advantage of public cloud cost savings.
What are the three tiers that comprise the three-tier architecture model?
The three tiers that comprise the three-tier architecture model are:
- Web/Presentation tier - Takes requests from web browsers and presents information to end users.
- Application tier - Houses business logic where processing takes place.
- Database tier - Comprised of database servers that store the processed data.
Describe the differences between a VPC and a VPN to someone you know from your previous job.
Hi friend, a virtual private cloud (VPC) creates a private, isolated network on shared public cloud infrastructure, giving you control over a virtual private data center. A VPN encrypts connections over the public internet to secure communications between locations. While you can set up a VPN connection to securely access resources within a VPC, a VPC itself provides built-in network isolation, granular access controls, and dedicated compute/storage resources instead of just an encrypted tunnel. A VPC is like having your own private condo in a shared apartment building, while a VPN lets you lock your own door within that shared space.
