Cloud Platforms: The Promise vs. The Reality

Recently our VP of Search, Michael McIntosh sat down and talked to me about his thoughts on cloud computing and what businesses should be aware of when investing in the cloud.


Karen: So, how does enterprise search and cloud computing fit together?  What’s good about it for companies?

Michael: The advent of cloud computing makes it a lot easier for companies to get into search without investing a huge sum of money up front. Some of the pay-as-you-go computing approaches make it possible to do things that in the past wouldn’t have been financially viable such as natural language processing on content.  Something that could have taken days, weeks, or even months can now take much less time by throwing more hardware at a problem for a shorter time span.

For example, you could throw 20 machines at a problem for 12 hours and do a bunch of computations in a massively parallel way, and then stop it as soon as it’s done….versus the old model where you have to buy all the hardware, or rent it, and make sure it’s not underutilized so you make your investment back.

But if you need a lot of processing power for a short amount of time, it’s really quite amazing what we can do now with an approach like this.

Karen: Is this a new technology for TNR?

Michael: TNR has been using cloud computing platforms for several years now—3 or 4 years.  Cloud computing in itself is sort of a buzz word, because distributed processing and hosting has been around for a while, but the pay-as-you-go computing model is relatively new. So we have a great deal of experience with the reality of cloud computing platforms vs. the promise of cloud computing platforms.

Karen: So, what is the difference between the “promise” and the “reality” of cloud computing platforms?

Michael: Well, A lot of people think of cloud computing as this magical thing; all their problems will be solved and it will be super dependable because there are very large businesses like Amazon running the underlying infrastructure and you don’t have to worry about it.

But, as the physical infrastructure becomes easier to deploy, other critical factors come into play. You won’t have to worry about the physical logistics of getting hardware in place. But, you will have to manage multiple instances, you have to make sure that when you provision temporary processing resources, you have to remember to retire it when it’s no longer needed. Otherwise you’ll be paying more than you need to. Since virtualization uses physical hardware you do not control or maintain—there are fewer warning signs to a potential systemic failure. Now Amazon, which is the one we use the most, does a good job of backing up instances and making things available to you even when there are failures. But we’ve had problems where we’ve lost entire zones. Even if we’ve had multiple machines configured with fault tolerance, Amazon has experienced outages that have taken entire regions offline despite every conservative effort to ensure continuous up time. So we’ve had our entire service clusters go down because of problems Amazon was having. It becomes critically important for companies to develop and maintain a disaster and recovery plan. Companies need to make sure things that are critical are backed up in multiple locations. Now historically, this has been hard to do because companies typically buy enough equipment for production needs, but not enough equipment for development and staging environments.

Karen: That sounds like a costly mistake.

Michael: It can be very costly because people often develop disaster recovery plans without ongoing testing to confirm the approach continues to work. If the approach is flawed, when you do suffer an outage, you can be offline for hours, days or weeks. Even worse, you may not be able to recover your data at all.

Karen: That sounds extremely costly.

Michael: Yes, it’s no fun at all.

There are upsides though. Some pluses are that cloud computing forces you to be more formal about how you manage your technical infrastructure. For example, for training purposes; with a new developer, we can just give them a copy of a production system, and have them go to town on it, make modifications, whatever without risking the actual production servers. And if they make a mistake, which is human (you have to factor in human error), you can reprovision a brand new one, and retire the one that is fouled up. Instead of having to spend hours and hours trying to fix the problem on the machine they were working on.

Karen: This sounds like it’s a lot more flexible and time efficient, with a layer of safety built in.

Michael: Yes. Cloud computing also comes in handy if you ever have a security breach. If a hacker gets into the system and the system is compromised–if this happens, system administrators can go in and try to correct the problem. But hackers can often install backdoors to get in and out. So a cloud platform with a good disaster contingency and backup can allow system administrators to bring a whole instance down and do the patch on a whole new machine without the security breaches and patches in place. This is pretty easy to do with a cloud platform.

Karen: So TNR can help their clients do all these things?

Michael: Yes, we’ve worked with large customers over many years and we’ve seen a wide variety of things that can possibly go wrong, and we’ve been through several physical service outages both with Amazon Web Services and with Rackspace.

Cloud computing in itself is no panacea, but if you have the technical and organization proficiency to effectively leverage the platform, it can be a powerful tool used to accelerate your company’s rate of innovation.

If you are assessing the cloud as a solution in your business, contact us.  There are a variety of options for hosting that can save your company money and minimize outages. Let us show you the option that is the best fit for your organization.
