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.

The Top 3 Private Networking Use Cases for CloudLink

Tuesday, April 2nd, 2013 by

Public clouds are fantastic for a majority of infrastructure use cases. And interconnectivity between clouds enables myriad solutions to empower businesses to have multiple synchronized points of presence across the world. Companies can easily set up connections that traverse the public Internet as a means to transmit and potentially synchronize data between cloud data centers. But these connections need to be reliable and more often than not, private.

With public network connections between clouds, users are at the mercy of hops and latency. For example, data may take one route with a particular number of hops, and a second later, may follow a completely different path and take a longer or shorter amount of time based on the connection.

In terms of securing the transport, some companies rely on point-to-point VPN connections using a hardware or software solution or some combination of the two. However, these solutions are also constrained by the connection and have limited speeds.

There are some scenarios or use cases that warrant using dedicated private networking to join geographically dispersed clouds. This is where GoGrid’s CloudLink service comes into play.

GoGrid’s CloudLink is a data center interconnect product—a redundant 10 Gbps pipe that is isolated to GoGrid traffic only. CloudLink enables private network traffic between different servers in GoGrid’s US data centers. As part of our “Complex Infrastructure Made Easy” mission, we designed this service to be basic yet powerful and still meet the needs of demanding organizations. Because this is a private network, much like the private network within GoGrid’s standard cloud infrastructure, there are no bandwidth costs. You simply decide on the connection speed (10 Mbps, 100 Mbps, or 1 Gbps), configure your connection, and pay for just the dedicated connection.

What is Auto-Scaling, How Does it Work, & Why Should I Use it?

Monday, March 11th, 2013 by

When I think about the phrase “auto-scaling,” for some reason it conjures up the word “Transformers.” For those not familiar with the Transformers genre of cartoons, toys, games, and movies, it is essentially about cars that turn into robots or vise versa, depending on how you look at it. When they need to fight or confront a challenge, Transformers will scale up from a vehicle (a car, truck, airplane, etc.) into a much larger robot. Then, when the challenge subsides, they scale back down to a vehicle.

Scaling Explained

Scaling – in terms of infrastructure – is a similar concept, but applied to the horizontal or vertical scaling of servers. Horizontal scaling means adding (or removing) servers within an infrastructure environment. Vertical scaling involves adding resources to an existing server (like RAM).

Let’s look at an example. An author of a content creation website may write an article that attracts the attention of the social media community. What starts as a few views of the article per minute, once shared by many in social media, may result in hundreds or thousands of requests for this article per minute. When this spike in demand occurs, the load to the server or servers handling the website’s content may experience extreme load, affecting its ability to respond in a timely manner. The results can vary from long page loads to the server actually crashing under the additional peak load. In the past, this scenario used to be known as the “Digg effect” or “Slashdot effect.”

Although this type of success is great publicity for the author, it’s bad for the brand hosting the content. And, if users encounter slow or inaccessible websites, they’re less likely to return for other content at a later point, which can eventually result in a loss of revenue.

Public Cloud Infrastructure Continues Gaining Momentum

Wednesday, March 6th, 2013 by

As the prospect of using cloud infrastructure technologies continues to influence decision-makers to adopt hosted services, companies are forced to choose which model they will implement: the private, public or hybrid network. In most cases, organizations are opting for the public cloud, because its multi-tenant environment and low buy-in opportunity lets firms of all sizes embrace the services.

A recent report by Gartner highlighted the progress of the public cloud, noting that it is forecast to generate roughly $131 billion in revenue in 2013, up 18.5 percent from the 2012 value of $111 billion. As executives gain more confidence in the cloud, they will leverage the solutions for a broader range of purposes, hoping to extend the value of the services to more departments and teams within the organization.

“The continued growth of the cloud services market will result from the adoption of cloud services for production systems and workloads, in addition to the development and testing scenarios that have led as the most prominent use case for public cloud services to date,” said Ed Anderson, research director at Gartner. “Evidence of this growth is found in the increasing demand for cloud services from end-user organizations, met by an increased supply of cloud services from suppliers.”

Some models garner more appreciation than others
Although the majority of the public cloud market is forecast to increase, certain segments of the industry will experience faster or more substantial growth than others. Because so many organizations are looking to augment storage, general computing and printing services, for example, the cloud infrastructure portion of the sector is forecast to develop quicker than other services.

Analysts said Infrastructure as a Service (IaaS) grew 42.4 percent in 2012 to generate $6.1 billion in revenue and this rate will continue into this year, expanding 47.3 percent to $9 billion in revenue. This rapid evolution will make IaaS the fastest-growing cloud segment of the global market.
