Cloud Network Security

Why does this topic matter?

• This topic matters because cloud solutions are here to stay, so it would be important for IT and cybersecurity professionals to know about the products the cloud can bring to an organization.

What are some of the key features of the VPC model?

• A VPC allows an enterprise the ability to define and control a virtual network that is logically isolated from other public cloud tenants, thereby creating a private, secure place on the public cloud.
  • One of the features of a VPC is agility, the ability to control the size of your virtual network and deploy cloud resources whenever your business needs them. Can scale resources dynamically and in real time.
  • Another feature is availability, this means that a VPC comes with redundant resources and highly fault-tolerant availability zone architectures, this means that applications and workloads are highly available.
  • Then there is the security feature, this relates back to how VPCs are logically isolated, so the data and applications won't share space or mix with those of the cloud provider's other customers.
  • Last is affordability, VPC customers can take advantage of the public cloud's cost-effectiveness, saving on hardware costs, labor times, and other resources.

What are the three tiers that comprise the three-tier architecture model?

• There is the web or presentation tier, which takes requests from web browsers and presents information created by or stored within, the other layers to end users.
• Then there is the application tier, which houses the business logic and is where most most processing takes place
• Lastly there is the database tier, this is comprised of database servers that store the data processed in the application tier.

Describe the differences between a VPC and a VPN to someone you know from your previous job.

• I would say that a VPC is like owning a private condominium in a Highrise apartment, you own a portion of the building that has other rooms, but only you have the key to the portion you own.
• A VPN is like a secure tunnel that only you can drive in, its secure and setup only to transport you and your car from point A to point B.

Things I want to know more about.

• I would like to know how businesses specialize VPCs
• Since you can use VPN as a Service to establish a secure site to site communication between multiple VPCs, I'd like to know how the setup for that works and how to implement it securely.
