Cloud Computing for Larger Companies – The Hybrid Approach
It’s interesting to continue to read the main stream technical / business journals that have articles on Cloud Computing, SaaS, outsourced application services, etc., and see that the approach is becoming more common sense in relation to what a company can do. We’ve seen this migrate from dramatic opinions one way or another back to the “best” approaches. I wrote about a Hybrid approach for larger companies back in the Spring, and we’re now seeing this implemented around the world.
So what does this really mean to the IT department in larger companies? It’s pretty straight forward if you think about each section of end customer need based on their requirements. Departments need access to applications that don’t go down. IT Service areas need to be able to maintain those systems. Global companies need straight-forward, cost-effective, access to centralized systems. And, everything needs to be up “almost” all the time…
The best way to solve these situations for companies relates to breaking down the different areas and systems by customer type and system type.
These are:
1. Enterprise wide high use systems (Email, SAP, Central Order Processing, etc.)
2. Large Departmental Applications (Accounting, Customer Service, CRM, …)
3. Enterprise wide File and Folder usage (Company wide information)
4. Departmental File and Folders (Typical departmental needs)
5. Web based systems (used by any customer group)
6. Individual Private File and Folder needs (the typical My Documents)
As we look at these requirements at the 50,000 foot level they appear straight-forward. Historically, IT departments are created to have centralized systems to serve these needs. Central application and database services, central file storage for all, central web applications, central email. One centralized large group that manages everything. But, as we all know, there are issues…
With a large centralized environment, concerns over the cost of disaster recover are huge. Additionally, with a Global footprint for the company, internal customers are not served best by on time-zone IT implementations. Poor service results. From the IT side, the issues develop around limited maintenance availability, on-call hours for key staff feeling more like working 20 hours a day, and overall high risk to the corporation. No great answer here.
If we move back to the thoughts of a Hybrid approach for this, what can we come up with that utilizes mainstream technology and satisfies user’s demand for uptime, speed, responsiveness? The answer is and has been in front of everyone’s eyes all along.
Break the systems up based on Section and deliver them in the best and most cost effective manner, PERIOD! Take the egos out of the IT department and develop a customer service mentality, PERIOD! Utilize scarce resources effectively to deliver the best for your internal and external system users, PERIOD!
1. Enterprise Wide Systems – These are perfect for the Cloud. Whether they utilize a web front end or are hosted and delivered in a thin client method (Citrix, Terminal Services), these belong in the cloud. It can be a shared redundant cloud, a “Private” cloud, what ever makes the most cost effective solution, but get them in the Cloud. What this does is moves the infrastructure out onto the best environment available for the applications. Servers (Virtual and/or Physical) can be turned up quickly, load balanced, replicated, and redundant. Applications can be delivered quickly and with great customer satisfaction based on the thin client model and still managed by staff from anywhere. Perfect!
2. Large Departmental Applications – Again, put them in the Cloud. Deal with them as if they were Enterprise Applications and your users will love you. Always available from anywhere, always up, delivered in a thin client method so that they can run when as where needed. Cost effective and rock solid. Perfect!
3. Enterprise Wide File and Folders – Split and Replicate only those needed. If we all view the amount of data that really is needed at an Enterprise level, it’s small. Might be 50 – 100 Gig that everyone needs access to. Could be via a document management solution or just replicated files based on whether the location runs local desktops or virtual desktops.
4. Department File and Folders – These also are based on the dispersion of users. If they’re all local to a location, local file and folders replicated for backup and redundancy are perfect. Disbursed locations, centralize those files and folders and provide virtual desktops to access them.
5. Web Based Systems – Always, always, hosted in the cloud. Redundant data, application, and web services as needed but always hosted. Let’s not think that “we” in the IT department should be building an empire around application infrastructure. It’s not cost effective, it doesn’t serve the enterprise, and it doesn’t take into account what’s best for the users.
6. Individual Private Files and Folders – These should be where ever your desktop is. If it’s a typical local desktop, then they should be mapped to a disk location at that physical location. If it’s a virtual desktop, then these are in the Cloud.
How do we make the decision on who gets a local typical desktop and who gets a virtual PC or virtual desktop? Good question. We believe it’s completely based on physical size (number of computer users) at the location. Less then 200, they’re getting a virtual desktop, 200 – 300, depends on local IT support, over 300, local desktop.
And here’s why this works so well. With smaller offices of less than 300 people, having distributed servers, file and folder disk, mail services, etc. just doesn’t make sense. It’s expensive, not redundant enough, and takes too much local IT resources to support. Users have more down time and less confidence in their ability to have access to key systems. By having these as all virtual, everyone has access to what they need with minimal IT local infrastructure and minimal IT support needs. Additional PCs, Macs, thin clients can be made available to anyone who has an issue. System doesn’t boot, grab another one and plug it in. It really is self service for local IT. With redundant connectivity, this solution is always up and available for the local users.
Over 300 people at a location moves to a little more gray area. Although you can sure run everyone virtual, there tends to be a need for more local IT support related to on-site hardware, routing, edge devices, etc. If there’s local staff, users could have the option of either way. Make sure centralized management of Group Policies and implemented, but this group could have full desktops. Again, management of local installed software takes time and money so weight that against the hosted version.
To wrap up, remember, there is a Hybrid approach where all applications/services are looked at and the best solution selected. Best must include costs, accessibility, redundancy, and other customer needs. Move the Enterprise and Departmental applications to the Cloud, move Files and Folders to the closest location for the user (Cloud for virtual PCs, local for local PCs), and realize that the Cloud and the services offered never make sense to duplicate at the corporate level. Outside of the Fortune 100, there’s no reason to become your own Cloud.
