Load Balancing Droplets from Digital Ocean

Load Balancing Droplets from Digital OceanWe recently helped a customer who had dozens of virtual machines (called Droplets) from Digital Ocean spanning multiple countries. Digital Ocean doesn’t have a load balancer, but even if they did, he was looking for a way to load balance traffic in each of 3 geographically diverse regions all without having to use DNS. He was using round-robin DNS to distribute the load among the group of servers, but it wasn’t working anywhere near the way he wanted it to, often distributing load unevenly.

Enable IPv6 with Cloud Load Balancing

Enable IPv6 with Cloud Load BalancingAs the global pool of IPv4 space continues to diminish every day, organizations are looking to deploy IPv6 at an ever increasing pace. But sometimes it's just plain difficult, especially when it requires a complete overhaul of your local network. Some organizations can implement dual-stack just fine, but for other organizations who host websites or applications at third party providers such as AWS EC2 and the like, IPv6 may not an option just yet.

VPN Load Balancing and Failover with two ISPs

VPN Load Balancing and Failover with two ISPsA common SSL or IPSEC VPN configuration scenario is one like we've shown in the (simplistic) diagram below. A corporate office has two incoming ISP connections, each with their own range of IP addresses. Clients or sites have VPN connections to the corporate office to access back-office devices in the LAN. The problem arises when the primary router or ISP goes offline. VPN tunnels that are configured using a DNS name don't fail over until DNS is updated, which is something our DNS Failover solution can nicely solve. But what about connections that rely on static IP addresses. I know Cisco ASA point-to-point VPNs require a fixed IP address, which is not uncommon amongst VPN hardware vendors. So what do you do in that case?

Our Cloud is Different Than Yours

Our Cloud is Different Than YoursA day doesn’t go by where we are yet again annoyed with how flippant organizations are in using the word “cloud” for what appears to be a marketing hype. Take Western Digital and their My Cloud product for which I have seen many TV commercials as of late. It is simply a personal cloud storage device. What’s really “cloud” about it? Other than the fact that you can access it remotely, nothing! It gives honest, legitimate cloud providers like Total Uptime a bad rap.

What are the key differences between DNS FAILOVER and CLOUD FAILOVER so I can better understand which one is right for my application?

Key differences between DNS Failover and Cloud FailoverThe Similarities: Both solutions require that you tell us what the IP address(es) are for your ‘real servers’. That way we know how to alter DNS or route traffic when one or more servers go up or down. These IP addresses must be publicly accessible, not private. Also, both solutions use the same type of...
