Amazon Elastic Compute Cloud (EC2) vs. Amazon Virtual Private Cloud (VPC)

Suitable for companies that are looking for performance at a competitive price, flexibility to switch instance type even with RI, flexibility to add-on IOPS, option to lower running cost with the regular introduction of new instance type that comes with higher performance but at a lower cost.

If you are going to deploy within AWS, you need to know how to leverage VPCs. VPCs have several items you must configure for them to be usable and to even link one VPC to another. If you are only going to deploy a few resources or use some of the default configurations, you still need to have working knowledge of how a VPC functions. If you are used to working with VLANs and the ideology behind those, that is the best direct reference to how a VPC can be described, but with additional layers on top of that with route tables, internet gateways, etc.

• Huge Diverse range of machine shapes are available which cater to our demand.
• Ability to combine the machines and integrate them with any other service in AWS (Ex: RDS, S3)
• Handling performance and scalability using auto-scaling, ELB configuration and high performance machine shapes.

• Pricing model & On demand service commitment.
• Well, architectural infrastructure development processing before spending the money.
• AWS VPC are providing hassle-free using with all others services from AWS very easily.
• AWS business support is very helpful & [gives] the right direction according to client’s situations.

• The choices on AMIs, instance types and additional configuration can be overwhelming for any non-DevOps person.
• The pricing information should be more clear (than only providing the hourly cost) when launching the instance. AWS DynamoDB gives an estimated monthly cost when creating tables, and I would love to see similar cost estimation showing on EC2 instances individually, as not all developers gets access to the actual bills.
• The term for reserving instances are at least 12 months. With instance types changing so fast and better instances coming out every other day, it's really hard to commit to an existing instance type for 1 or more years at a time.

• The biggest issue with VPC networks is knowing how you can leverage VPC endpoints to ensure your resources within the VPC are not reaching out over the Internet to get to AWS services such as S3 and others.

You an start using EC2 instances immediately, is so easy and intuitive to start using them, EC2 has wizard to create the EC2 instances in the web browser or if you are code savvy you can create them with simple line in the CLI or using an SDK. Once you are comfortable using EC2, you can even automate the process.

AWS's support is good overall. Not outstanding, but better than average. We have had very little reason to engage with AWS support but in our limited experience, the staff has been knowledgeable, timely and helpful. The only negative is actually initiating a service request can be a bit of a pain.

Amazon EC2 is super flexible compared to the PaaS offerings like Heroku Platform and Google App Engine since with Amazon EC2, we have access to the terminal. In terms of pricing, it's basically just the same as Google Compute Engine. The deciding factor is Amazon EC2's native integration with other AWS services since they're all in the same cloud platform.

• It reduced the need for heavy on-premises instances. Also, it completely eliminates maintenance of the machine. Their SLA criteria are also matching business needs. Overall IAAS is the best option when information is not so crucial to post on the cloud.
• It makes both horizontal and vertical scaling really easy. This keeps your infrastructure up and running even while you are increasing the capacity or facing more traffic. This leads to having better customer satisfaction.
• If you do not choose your instance type suitable for your business, it may incur lots of extra costs.

• AWS VPCs are actively used for following various compliance and regulatory needs such as network separation for PCI DSS. The ability to keep resources and access to those resources controlled through the initial steps of creating VPCs has helped tremendously.
