In the world of cloud computing, the ability to efficiently and securely route internal traffic is paramount for businesses that rely on cloud-native applications. This functionality is crucial for scaling private workloads, optimizing resource use, maintaining data security, and enhancing the overall performance of applications. To address these needs, DigitalOcean has introduced its Internal Load Balancer (ILB) in an early access phase. This innovative tool is a regional load balancer specifically designed to help businesses scale their internal workloads seamlessly.

Understanding DigitalOcean’s Internal Load Balancer

DigitalOcean’s Internal Load Balancer is engineered to distribute incoming HTTP, TCP, or UDP traffic across your Droplets and Kubernetes (DOKS) clusters using private IP addresses. This approach significantly reduces the exposure of your services to the public internet, thereby enhancing the security of your internal operations.

Prior to the introduction of the Internal Load Balancer, private load balancing on DigitalOcean was a complex task that required cumbersome workarounds. Users often had to manage proxy software such as Nginx or HAProxy manually on a Droplet or rely on an external load balancer combined with firewall rules to limit public access. While these methods were functional, they involved extra configuration, maintenance, and overhead, complicating the process of scaling internal workloads.

With the introduction of the Internal Load Balancer, scaling internal workloads becomes a much simpler process. This load balancer is designed to streamline internal traffic routing while maintaining high levels of security and performance. Developers can now scale their private workloads without exposing traffic to the public internet by avoiding the use of public IPv4 addresses. This feature is especially beneficial for small and medium-sized businesses (SMBs) looking to scale private workloads within a Virtual Private Cloud (VPC) or scale application tiers using a private IP.

Key Features of the Internal Load Balancer

The Internal Load Balancer offers a suite of features designed to simplify management, enhance security, and improve scalability. Here’s a closer look at what users can expect:

1. Simplified Management: The Internal Load Balancer allows users to create and manage it with just a few clicks, eliminating the need for manual workarounds. This ease of use enables businesses to quickly scale their private workloads without unnecessary complexity.
2. Private Load Balancing: By using private IPs, the Internal Load Balancer distributes traffic in a manner that ensures internal workloads remain secure and protected from the public internet. Unlike the HTTP Load Balancer, the ILB is exclusively built with private IPs, offering an additional layer of security.
3. Secured Global Scaling: When combined with DigitalOcean’s Global Load Balancer (GLB), the Internal Load Balancer allows for global scaling of workloads while ensuring backend services remain scalable, secure, and isolated. This capability is vital for businesses with a global presence seeking to maintain seamless operations across different regions.
4. VPC Peering Support: The Internal Load Balancer supports VPC peering, which enables secure and private communication between services or pods across different VPCs. This feature is crucial for organizations that operate multiple VPCs and require seamless interaction between them.
5. DOKS Service Connectivity: The Internal Load Balancer allows users to expose DOKS services over the VPC network, keeping traffic internal. For those utilizing Kubernetes, this feature is invaluable as it maintains the integrity and security of internal traffic.
