Is Your High-Tech Company Ready For An SDN-Enabled Cloud?

Thursday, April 18th, 2013 by

When it comes to technology, there are many companies on the “bleeding edge” these days. Sometimes these companies achieve greatness by being visionary, producing products or services that others haven’t thought of, or investing heavily in R&D. But they all have one thing in common: They use the latest high-tech, innovative solutions to power their journeys.

When it comes to the underlying infrastructure powering a technology-oriented company, “cutting edge” means success. Sites and services need to perform, be reliable, be resilient, and have the flexibility to expand and contract based on the ebb and flow of day-to-day business. For me, that means cloud infrastructure is the best solution for companies looking to stay ahead of the curve.

Over the past few months, GoGrid has released a variety of services and features designed to give companies a leg up on the competition. It’s all centered on providing cloud infrastructure that’s flexible, yet forward-thinking. It’s much more than simply needing faster and bigger clouds—it’s about architecting our cloud solutions to provide customers with a highly available and distributed set of infrastructure components. And it’s architected according to software-defined networking (SDN) concepts.

SDN architecture isn’t focused on internetworked commodity hardware or new ways to provide networking services. It’s designed to distribute a variety of formerly hardware-based solutions across nodes, data centers, and clouds. When you think about “old school” infrastructure architecture, you probably think of physical devices. And if you think about one device, you really need to think about two, for redundancy and backup. If your hardware load balancer or firewall fails, you have to be sure you have a warm or hot standby available to immediately take its place. That requires time and money. And if you want to be cutting edge, you don’t want to be spending your precious time and money planning for the inevitable. You want to be innovating and iterating.

That’s where SDN is truly powerful and why many of the leading technology companies are adopting solutions that use it. With SDN, you can build in fault tolerance and redundancy. Take our recently released Dynamic Load Balancers as an example. Instead of relying on a single hardware device for routing traffic between available servers, our Dynamic Load Balancers are distributed and highly available across our Public Cloud. If one of the Dynamic Load Balancers fails, another instance, complete with configurations, is spawned immediately elsewhere thanks to our self-healing design. And these load-balancing services can be controlled programmatically via our API.

This month we announced another service that operates in the same distributed manner, our Firewall Service. Although many companies choose to use Cisco ASAs as a security front end for their cloud and physical infrastructure environments (an offering we also provide), these are physical devices that require management. However, our SDN architecture lets us provide more resilient and creative solutions. Like our Dynamic Load Balancers, our Firewall Service is built around SDN concepts and distributed across nodes and our data centers. When you create a security group (that has policies assigned to it), it’s automatically replicated across all our data centers within seconds. If you have distributed infrastructure, you can simply assign a security group to any similarly configured Cloud Server, regardless of that server’s location. If you subsequently change a policy, it’s automatically synchronized to all servers across all data centers that are part of that security group. In other words, you configure once, assign the security group to the server(s), and then watch the SDN magic happen.

How To Create a Distributed, Reliable, & Fault-Tolerant GoGrid Dynamic Load Balancer

Tuesday, February 26th, 2013 by

As Rupert Tagnipes outlined in his article “High Availability with Dynamic Load Balancers,” crafting a fault-tolerant, reliable website is critical to a company’s online success. There’s nothing worse than going to a website to do a transaction only to have it either be slow to respond or have an interaction time out. By setting up a load balancer in front of transactional web or application servers, companies can ensure their web presence is resilient, responsive, and gets information to their customers reliably.

GoGrid launched with a free load-balancing service in 2008. This year, we introduced our next-generation cloud load-balancing service on GoGrid. Embracing the software-defined networking (SDN) mantra, we created our load-balancing service to embrace the key characteristics of cloud computing: on-demand, usage-based, and distributed. I encourage you to read more about our Dynamic Load-Balancing service in Rupert’s article.

Although understanding why load balancing is critical to success is important, knowing how to create a new GoGrid Dynamic Load Balancer is equally important. This How-To article will guide you quickly and easily down that path.

As always, I like to boil the process down to 3 easy steps. In the case of the Dynamic Load Balancer creation process, these steps are:

How to Configure Zeus’ New Load Balancer in the GoGrid Cloud

Wednesday, September 14th, 2011 by

Zeus is a new GoGrid partner that provides a software load balancing product as a partner image called “Zeus Load Balancer 200Mbps”. There are three immediate features that come to mind when thinking about how to leverage Zeus within GoGrid: Load Balancing, Failover and Clustering. Note that this first image is a preview with certain feature set. It contains the majority of Zeus features but is capped at two clustered servers and 200 Mbits of bandwidth. Additional images are expected to be released by the end of the year.

This tutorial assumes that you have basic understanding of Linux and SSH as well as basic load balancing and failover strategies.

Cross Data Center Load Balancing / Failover

One of the main uses cases for Zeus is to load balance servers in the same data center. However, a more interesting use case is to quickly and easily load balance web servers within one data center and support failover to another data center. The process is straight forward. First, deploy the Zeus partner image as a VM with 1G RAM in the US-West-1. This example assumes that you already have web servers running on both the US-West-1 and US-East-1 data centers.

Once the Zeus image has been deployed, SSH into the server using the root login. Your logins can be found in the GoGrid web portal by clicking on the server icon, then Tools > Passwords.

We recommend changing your automatically created, default password as soon as you login.

The Importance of Building Your Cloud Infrastructure the RIGHT Way

Thursday, July 21st, 2011 by

The cloud is great for so many things. You can create a web presence in a matter of hours or completely implement an N-tiered, redundant, elastic, secure globally-available cloud topology. Spinning up infrastructure via a web portal or API in minutes via a few clicks of a mouse is a dramatic transformation from the days of racking and stacking servers, untangling miles of cat5/6 cables, connecting load balancers and firewalls to the mix and hooking up storage devices. And let’s not forget about physical security, power supplies, cooling and network redundancy. The neat thing about the cloud is that all of the stuff has become really easy to do and you can do it very quickly.

GoGrid has a long history of enabling IT infrastructure solutions for companies across the world. We have built out core services and offerings to allow businesses to build want they want quickly, efficiently and with state-of-the-art cloud technology. But just because you have great tools at your disposal doesn’t mean that your cloud environment will magically create itself. And that is something that we realize and understand at GoGrid.

Architect for Success

Cloud computing can be almost magical at times, but we need to remember the processes and best practices for security and ensuring redundancy that we are accustomed to using, and adapt and use them within the cloud as well.

A few weeks ago, I wrote a post “Things to Think About When Building Secure Infrastructure” where I made a few points about “assumption,” namely, assuming that whatever cloud vendor you choose, they will take care of everything for you. Regardless of the cloud vendor, you need to do your due diligence and update your standard operating procedures to reflect how cloud computing works. It is different than traditional IT in many ways. For example, in the GoGrid cloud, you can create a cloud server, harden it with security software and configurations and then save it as a MyGSI (as “server image”). Then, as you need to scale out your infrastructure, you can do this not only quickly, but securely as well, by deploying clones or instances of that hardened server. With a traditional, physical deployment, it takes much longer and there is no guarantee that you will have each and every security patch in place on every server.
