CIOs and IT managers are slowly realizing the benefits of Cloud Computing but there’s still a long ways to go. Product offerings for hosted services have matured and exploded but there are so many options now that it’s hard for IT management to keep up.
So, here’s a quick guide to the Cloud technologies that are out there. I’ve broken it out in to the three major Cloud services areas to help you better understand what’s available and how:
- IaaS (Infrastructure as a Service) or HaaS (Hardware as a Service)
- PaaS (Platform as a Service)
- SaaS (Software as a Service)
Infrastructure as a Service
* In a nutshell: you pay for full access to a server that someone else hosts for a monthly fee. These services generally include some sort of terminal access to a virtual computer instance that you populate with your own operating system and software license. Often, you’ll access the server through a terminal service client of some sort. *Note: HaaS often is confused with IaaS and generally refers to on site (not Cloud) equipment provided along with support services by a service provider for a monthly fee rather than as an up front capital investment.
* Who needs it: anyone that needs full configuration capability for a server but doesn’t want to actually host the server themselves.
* Benefits: host equipment so you don’t need to build your own Tier-1 datacenter for access to a highly reliable and secure environment.
* Challenges: even though you have full access to the “box” your applications are deployed on the “box” may actually be a virtual server rather than a full server… limiting the configurations on the actual hosting hardware. If you’re trying to move a locally hosted server to the Cloud the performance may not be the same since your connection now goes over the internet.
Platform as a Service
* In a nutshell: highly-reliable hosted operating system software that totally obscures the hardware infrastructure. Services may be accessed through a web browser or application client of some sort.
* Who needs it: application developers that need a platform (.NET for instance) for their applications but do not require complicated customized infrastructure. Anyone who wants their application to “scale” quickly on a fully virtualized platform without downtime for software and hardware upgrades.
* Benefits: the infrastructure disappears. You get a reliable and scalable service for a monthly fee.
* Challenges: customization of the platform may be restricted to enable broad use by many types of applications. You may not have all the options you would like. Some PaaS services do not provide all the debugging, test and development tools you’ll need or may use tools you’re unfamiliar with.
Software as a Service
* In a nutshell: perhaps the first and most recognizable of the cloud services, SaaS obscures the whole back end and simply provides a web-based application generally accessed through a web browser.
* Who needs it: anyone wanting to host a highly reliable web site or service generally accessed through a browser like Internet Explorer or Firefox. Some applications may be quite complex and may even interface with hosted databases and other web services but require no access to the underlying operating system or hardware on their own.
* Benefits: the cheapest and least complex platform and also the easiest to develop for. Applications can be deployed very quickly.
* Challenges: configuration options are often accessed through a web console and are limited in scope.
There’s something for everyone in Cloud computing. With so many options, the question is not whether you need Cloud computing any more, but WHERE you need Cloud computing. Many companies are taking baby steps in to the technology through obvious Cloud computing targets like hosted e-mail and CRM. Especially small and medium sized companies that have difficulty investing capital in secure, highly reliable onsite infrastructure will be interested in the opportunities that Cloud computing presents.
Even large enterprises can find Cloud computing synergies. How powerful would it be to pay a monthly fee for an application you don’t need to deploy across hundreds or even thousands of desktops? Wouldn’t it be nice to simply deploy a shortcut to a hosted application instead? There would be no need for internal development and no need for additional help desk resources.
If you’re a CIO or IT manager, do yourself a favor. Get educated and get moving. The Cloud is here like it or not.
The Small & Medium Business Case for Office 365 – An Evaluation of Microsoft’s Cloud E-mail and Collaboration Services
For some background on Office 365 see my previous post http://blog.redwoodnetworks.com/2011/04/what-makes-sense-in-cloud-today.html. I’ll assume that everyone is passing familiar with hosted e-mail and collaboration services for the purposes of this article though.
Like Punxsutawney Phil, the economy saw its shadow in 2010 and returned to its hole for another 6 weeks (months) of winter. Spring is here now, though. Businesses are spending money and hiring again and they’ve learned a few things. First of all, they’re a little more cautious… especially with regards to technology and purchasing systems that require a great deal of ongoing maintenance. They continue to be interested in new ways of doing more with less. What’s new, though, is that they are willing to take some calculated risks, give some new ideas a try.
I’m going to make some generalizations about businesses… see if any of this sounds like your business:
- You have limited capital assets to invest on computer technology, software and services.
- You need to keep up with technology trends within reason… to keep in line with vendors, partners, clients, etc.
- You require solutions that are reliable, business tested, and easy to manage.
- You have one or more in house computer servers now providing e-mail and collaboration services.
- Your organization includes several people that require the ability to not only send e-mail but to collaborate with each other and external users efficiently.
- You’ve delayed renewing your systems for the last couple years due to the recession but you just can’t wait any more. Your systems are aging and it’s just time to upgrade.
Does any of this sound familiar? If so, this is a great time for you to evaluate some of the maturing solutions for hosted e-mail and collaboration services. Small and medium-sized business have had it hammered in to their heads over the last 10 years that they can now do all the things that large businesses can do with technology: they can have their own e-mail; they can have web portals, not just plain old websites; they can host web training and deliver presentations to hundreds remotely; they can have instant messaging and unified communications systems that deliver voicemail messages to their e-mail inboxes.
There’s a problem though. All of these solutions require a LOT of maintenance. And experts to maintain them. Not to mention that the solutions themselves are not cheap. They’re much more affordable than they used to be, but it’s still hard to part with capital. Didn’t we just have a recession? And are we really SURE it’s done? How can businesses take advantage of all of these technologies that extend productivity and give critical advantages over competition… but do it without the large investments and risky baggage they come with?
Well, they’re in luck. If you really have been hiding in a hole for the last 3 or 4 years you’ve missed a revolution in computer technology. It’s called Cloud Computing and Microsoft is there in spades with their new Office 365 product. When I say new though, don’t get the wrong idea. This is not a version 1 product. Hosted e-mail and collaboration services have been around for several years now.
Back to the business case for Office 365 then. Let’s talk about some of the reasons why businesses have NOT been moving in droves to hosted cloud services up to now.
Road Block #1: The Solutions are Just Not Mature.
Your business cannot depend on a hosted service you cannot control. Hosted solutions aren’t reliable and are probably not secure. Also, the service level agreements are not sufficient and they’re just not ready for prime time.
Microsoft deployed its first hosted Exchange e-mail service (the 1.0 product) in 2002, re-released it in 2006 (Exchange Hosted Services – the 2.0 product) and expanded it to include the collaboration product Sharepoint 2007 (Exchange and Sharepoint Online – the 3.0 product), finally reaching the current product – Business Productivity Online Services (or BPOS – the 4.0 product) in November 2008. Office 365 is expected to release fully in the US around mid-year 2011.
So, if you look at the full history of hosted Microsoft online services, Office 365 is most definitely NOT a version 1 or even version 2 product. It’s a mature and well-thought-out suite of services with offerings that are appealing to a broad range of business types and sizes. With everyone’s concern (often for good reason) over trying version 1 products it’s important to understand just how mature hosted “cloud” services have become over the last 5 years.
Road Block #2: Access to Adequate Internet Connections
Up until recently, many small businesses struggled with obtaining reliable and speedy internet service. This kept them from considering hosted solutions because of the perceived low quality of those services.
With the expansion of cable companies in to the business space and the resulting innovation by the phone companies, small businesses now have extraordinary options for high-speed, reliable internet services. T1? Old news. Got fiber? No? Check it out.
Road Block #3: Didn’t We Buy that Last Year?
Pre-existing investments by medium-sized businesses in some of the very technologies being moved to the cloud have kept them from fully investigating outsourcing those services. There’s a lot of infrastructure that was purchased to enable some of these solutions and you can’t just throw it away!
Microsoft Office Communications (OCS) server and Sharepoint have both experienced a renaissance in medium businesses over the last 5 years. Integration of phone systems with OCSSharepoint has become a major productivity tool on par with e-mail in many offices.
Many of these investments are now aging. Staff has been downsized during the recession. Businesses want to keep these capabilities but do it with less staff and capital investment in infrastructure that needs refreshing every three to five years. The online solutions have matured and now offer many if not all of the same features as their more traditional cousins. If it’s time for a tech refresh, it’s time for an online services evaluation!
So, with most of the major road blocks removed, why haven’t businesses been moving to the cloud in droves? Expertise. The industry requires a new generation of consultants and engineers that specialize in Cloud Infrastructure Services. They’re coming, believe me. Those who see the writing on the wall are already well in to delivering these services to their clients, but full penetration will take some time yet. There is a fundamental shift in how Information Technology is delivered. Microsoft calls it “Software Plus Services.” You won’t see onsite computer servers, software and services disappear from businesses entirely, at least not for a long while. But, the slow movement of services to the cloud has begun and will only accelerate.
Back to the business case again then. You can now:
- Pay for your e-mail, collaboration portal, instant messaging, and meeting/web conferencing solutions via a monthly subscription that is a true expense and saves you from calculating depreciation of assets.
- Obtain all of these services without a major capital investment.
- Bring capabilities that only large enterprises previously had available to small and medium businesses quickly and easily.
- Future-proof your technology – don’t invest in new technology that will be obsolete again within 5 years. These services include all upgrades – performed invisibly in the background and without major interruptions (mostly) in service.
- Access services from anywhere – it’s incredibly easy now to open a new office. Who cares about connecting to the servers in your old office, it’s all hosted online!
- Access more and better solutions – the rate of development for new applications, services and solutions on the web is much faster than the traditional model. A company can create a product and have it deployed to customers overnight now. React faster with more relevant solutions than ever before.
- Right-size your solutions. Need more seats? Add them and they’re available within minutes. Downsize? Remove some seats and pay less next month. This is an absolute revelation to seasonal businesses.
How much does all this cost? An arm and a leg, right? Not at all! The entry level product with 99.9% guaranteed uptime and limited support is available for only $6 per user per month. For larger businesses with more substantial needs or those with higher SLA requirements there are solutions that range in price up to $27 per user per month. The upper-level options also include a license of Microsoft Office Professional Plus for each user. This is yet another way to move a capital expenditure in to the expense category.
So, while not every “cloud” offering is worth evaluating, the Microsoft Office 365 services coming to market in the next several months are mature services worth a hard look by small and medium-sized businesses. Cloud services are ready and they’re here. You should be actively looking at them and figuring out how they will change your business. You can be sure that your competitors are.
