We decided that we would like to be able to change server states and bring them online, offline or drain them. So asking Alexa to do this would look like “Alexa ask Val to change status of website1 to drain”. So we started work with this as our goal.
After the recent introduction of Enterprise Ultra to our hardware family, plus the recent software update 8.2.4. We are pleased to finally announce our new Voice Activated Load Balancer - Enterprise VAL.
For several years, if an instance was launched in AWS and during the initial configuration an IAM role was not defined, the only option available was to stop/terminate the instance and launch another, however, this has now changed!
The stability of the Loadbalancer.org products enables DelftDI to ensure the high availability of its medical imaging solutions.
I am going to focus on how simple it is to mitigate it when using the SSL termination/offloading options available on a Loadbalancer.org appliance.
The appliance works quite nicely in a oVirt environment and should work just as well with a full Red Hat’s Enterprise Virtualization environment (RHEV)!
Follow the instructions below to install and configure the external health check, and once you've completed the steps you can use the health check for either layer 4 (LVS) or layer 7 (HAproxy) clusters.
A pair of F5s is a great solution, but mainly if you need to run a crazy number of applications and servers through a single device. In that case, you definitely need an expensive, complicated, over-specified and over-engineered single point of failure.
HAProxy Technologies' ALOHA Pocket is a full-featured ALOHA Load Balancer running on a light USB-powered hardware that easily fits in a pocket, meaning it's possible to carry it everywhere to run tests and demos.
Let’s Encrypt offers us a free way to get SSL certificates with the aim of being less complex than other current solutions.
In part one we were introduced to Polaris-GSLB which is a cool little open source GSLB solution. In part two of this Blog I’m going to show you how to build Polaris-GSLB on CentOS 7.
Here at Loadbalancer.org we’re not known for being huge fans of GSLB solutions as some of our customers may already know.
We engaged in some great conversations with people over the two days. This is why we love IP EXPO - talking through the problems customers are experiencing today.
The Web Application Firewall is based on ModSecurity which is an open source WAF for Apache, IIS, and Nginx for protecting against a many variety of attacks and allows for HTTP traffic monitoring and logging.
HAProxy is an excellent choice if you need layer 7 functionality, but its a full reverse-proxy, so the application thinks that all of the traffic is coming from HAProxys IP - rather than the clients.
We can write custom health checks specific to your environment checking availability of servers as well as other backend systems such as REST servers, databases and storage.
SNI is an extension to the TLS protocol which enables the client to broadcast its hostname when it tries to connect to your server. This allows you to use multiple SSL certificates on a single IP.
This was Loadbalancer.org's first time exhibiting at the Manchester version of IP EXPO. After many years attending the London event, we can safely confirm that the Northerners are a much more chatty bunch.
The Loadbalancer.org for AWS appliance will monitor auto scaling groups, update configs based on auto scaling events and add/remove servers.
We met lots of people and gave away a lot of lanyards...in fact the show organizers ran out of lanyards, so Loadbalancer.org were happy to fill the void.
Once HAProxy is running transparently, it will allow the real server to see the client IP so the real server will reply directly back to the client bypassing the load balancer.
Using the flexibility of both AWS and our Enterprise AWS appliance, it's possible to configure a secure and robust load balanced Remote Desktop Services deployment to suit a range of requirements.
Policy Based Routing is a clever way to give us more control over which routing path connections will take. It allows us to specify custom routing tables and then add rules offering fine grained control over which routing table a connection will use.
Loadbalancer.org is 13 years old, and we thought it was about time we bought our very own office building! Anyone who has visited our current UK office at the Technopole Portsmouth, will understand why we were feeling a bit claustrophobic. We have spent a very happy 7 years here
Due to the way that PuTTY uses a signed integer variable to store the number of characters to be erased and there was inadequate checking for overflow, there was the potential for an attacker to corrupt important data in certain circumstances.
