Hey there! If you‘re looking to build a secure cloud infrastructure, using a virtual private cloud (VPC) is one of the best options available today. In this comprehensive guide, I‘ll provide you with a deep dive into VPCs – what they are, key benefits, top providers, architectures, and recommendations for finding the ideal platform based on your needs.
As an infrastructure architect and cloud technology enthusiast, I‘ve worked with a wide range of public cloud and VPC environments. I‘m excited to share my insights with you so you can make an informed decision on the best virtual private cloud. Let‘s get started!
Demystifying the Virtual Private Cloud
A virtual private cloud essentially creates a private, isolated section within a public cloud. It provides you complete control to define and manage your own virtual network comprised of compute, storage, networking and security resources.
According to Gartner, over 75% of mid to large-size enterprises will adopt a multi-cloud or hybrid IT strategy by 2022. VPCs are becoming the go-to approach for securely implementing these strategies.
So why are VPCs gaining rapid traction? Here are some key reasons:
Enhanced Security
VPCs provide network isolation for your infrastructure, preventing access from other cloud tenants. You can use security policies like network ACLs and security groups to tightly restrict inbound and outbound connectivity. Sensitive data stays protected within your virtual private network.
Greater Control
You have complete administrative control within your VPC to define subnets, IP addressing, route tables, and network gateways. Essentially, you can design the network architecture within your VPC based on application requirements.
Flexible Access
While VPCs provide isolation, you can still enable controlled access to resources in your VPC by setting up VPN tunnels and direct connect links between your VPC and corporate network. Hybrid connectivity becomes seamless.
Scalability
VPCs offer seamless, on-demand scalability since they leverage the vast capacity of the public cloud. You can dynamically scale your VPC resources like subnets and IP addresses based on usage.
Cost Savings
You only pay for the specific VPC resources you use like virtual servers and storage. The pay-as-you-go model provides significant cost savings compared to purchasing dedicated hardware.
Clearly, VPCs provide the best of both worlds – private cloud security with public cloud agility and economics. Now let‘s explore the leading VPC platforms.
Top 8 Virtual Private Cloud Providers
I‘ve handpicked the top 8 VPC offerings based on capabilities, maturity, and real-world usage across enterprise infrastructures.
1. Amazon Virtual Private Cloud
Amazon Web Services dominates the public cloud market, so it‘s no surprise that Amazon VPC is the most widely used virtual private cloud platform. Thousands of customers have deployed Amazon VPC to isolate their networks on AWS.
Amazon VPC makes it easy for you to define a virtual network topology with public and private subnets. You get granular control over IP addressing, route tables, network gateways, and DHCP options.
Security groups act as virtual firewalls to restrict inbound and outbound network access to Amazon EC2 instances. Network access control lists (ACLs) provide an additional layer of protection at the subnet level.
You can establish VPN connections between your Amazon VPC and on-premise data centers using AWS virtual private gateway. This enables a seamless hybrid infrastructure.
Direct Connect lets you establish private, dedicated connections from your corporate network to Amazon VPC bypassing the public internet.
According to Gartner‘s Magic Quadrant for Cloud Infrastructure and Platform Services, Amazon VPC is the most mature, enterprise-ready virtual private cloud solution:
"AWS provides, by far, the most comprehensive capabilities across all customers requirements, supporting infrastructure at scale, packaged solutions for specific needs, and a wide range of tools to enable customer self-service."
With Amazon VPC, you get access to AWS‘s market-leading services while maintaining isolation and full control – clearly a winning combination!
2. Microsoft Azure Virtual Network
Microsoft Azure comes second after AWS in terms of public cloud adoption. The Azure Virtual Network (VNet) service provides similar VPC capabilities within the Azure environment.
Like Amazon VPC, Azure VNet allows you to fully customize virtual networks with reserved private IP address ranges, subnets, route tables, and network security policies.
VNet supports isolating your Azure infrastructure through network segmentation and security groups. You can tightly control traffic flows between different resource groups in your VNet.
Azure VPN Gateway can be used to establish site-to-site VPN connections between your VNet and on-premise network. ExpressRoute provides direct private connections for hybrid environments.
VNet Peering allows connecting VNets across Azure regions to build global, high-scale network topologies. Dynamic routing between VNets is natively supported.
According toRightScale‘s 2021 State of the Cloud report, 72% of enterprises are running applications on Azure, second only to AWS at 82%. With Azure VNet, you can take advantage of Azure‘s broad range of cloud services while maintaining complete control.
3. Google Virtual Private Cloud
Google Cloud Platform has firmly established itself as one of the top three public cloud providers. Google Virtual Private Cloud (VPC) is the native VPC offering within Google Cloud.
Google VPC provides a software-defined virtual network that you can customize with subnets, firewalls, routes, and VPN gateways. You can deploy resources like GKE clusters, Bigtable instances, and Cloud SQL databases within your VPC.
A unique capability is Shared VPC that allows resources from multiple projects to access a common VPC network. This simplifies cross-project connectivity and sharing.
Google VPC supports hybrid connectivity to on-premise environments through Cloud VPN and Cloud Interconnect. Traffic stays private and isolated from the public internet.
Overall, Google VPC makes it easy to deploy resources across a customizable virtual network on Google Cloud. It keeps your infrastructure isolated while enabling controlled external connectivity.
4. Oracle Cloud VMware Solution
Now let‘s look beyond the big three public clouds. Oracle Cloud VMware Solution (OCVS) provides a seamless way to run VMware workloads natively on Oracle Cloud Infrastructure.
OCVS allows you to deploy the familiar vSphere stack on dedicated, bare metal Oracle Cloud instances. You get full access to vCenter Server to manage ESXi hosts, virtual networking, storage policies, and VMware tools.
A key benefit is that you don‘t need to re-architect VMware-based applications to migrate them to the cloud. You simply move them as-is to OCVS and avoid any application changes.
OCVS makes it easy to scale resources by adding more hosts to the cluster. You can modernize applications by connecting OCVS to native Oracle Cloud services. With OCVS, you get cloud elasticity and agility for VMware-based workloads.
