Understanding The Cloud Computing Infrastructure
Grazed from CloudTweaks. Author: Abdul Salam.
As a long time advocate of cloud computing, I already know most of the technology and terms surrounding cloud computing and if someone mentions a new application or feature I might be able to gleam how it works based on the technologies used. This is not necessarily true for most people even if they have been in the IT industry for a long time. That is why I write “simple” articles that the less informed might be able to grasp easily. But to get a real understanding of something, you need to get an understanding of its internal structure, understand how it works and not just what it does. If someone tells you that an airplane flies because of engines and wings, it will still seem like magic because you are not really informed on the how. Same as cloud computing, for many it simply provides them with that service that they take for granted without really knowing how it is done. And to understand it better, we must understand the underlying infrastructure of cloud computing.
To put it simply, the infrastructure or how all the hardware technology and other elements come together cloud computing is very similar to that of traditional network computing. You have your servers that contain the CPUs, RAM, and other processing elements, and then you have your various storage devices like NAS and RAID-style setups. Of course, to round out the bunch you have your networking hardware, the routers, switches, modems, repeaters, and any and all combinations of networking hardware technology. If you look at the list I just mentioned, it is obvious that the hardware used for cloud computing has been existing, but why hasn’t cloud computing existed as long?…
Google is encouraging users of its Google Drive online storage service to go paperless in 2013 as a way to save time, money and trees. "This year, Google Drive is part of the Paperless Coalition, a group of organizations and products that help you live completely in a paper-free world," declared Google product marketing manager Meredith Blackwell in a blog post. "So whether you’re an expense reporter, invoice tracker, file hoarder or note jotter, you can do it all without using paper."
The largest retailers and the smallest online merchants bemoan the power Amazon wields in retail, but the company also has tech firms racing to keep up. Over the years, Amazon developed expertise building its own retail site, and in 2006, Amazon Web Services (AWS) began offering IT infrastructure services to other businesses in the form of web services – now commonly known as cloud computing.
Hewlett-Packard, which is desperately seeking ways to get its boat off the sandbar, told the SEC last week in its annual 10-K that "we continue to evaluate the potential disposition of assets and businesses that may no longer help us meet our objectives."
RiverMeadow Software Inc., developer of the RiverMeadow cloud migration SaaS, the world’s only automated server migration solution developed specifically for Carrier and Service Provider Clouds, today announced it will offer its cloud migration SaaS to VMware Service Provider Program (VSPP) partners.
LabTech Software, the remote monitoring and management (RMM) software company, is working on two specific cloud computing strategies to empower MSPs over the long haul. The first involves integrated, end-to-end cloud solutions that MSPs can offer their customers. The second involves integrated capabilities that allow MSPs to provision, monitor and bill for those services. CEO Matt Nachtrab offered MSPmentor some deeper thoughts about the strategy during a recent email exchange. I’m starting to wonder: Will LabTech and/or sister company ConnectWise emerge as a cloud aggregator — allowing MSPs to source and manage a range of third-party cloud services for customers? Here’s the update.
Cloud builders that use VCE Vblock as the central piece to their cloud puzzle have a new tool available in their kits. VMTurbo, which makes intelligent workload management software for cloud and virtualized environments, has managed to receive VCE Vblock Ready certification for its VMTurbo Operations Manager.
Research In Motion (RIM) has let go of its cloud services company, NewBay, selling it to Synchronoss Technologies for $55.5 million in cash. The acquisition closed just after Santa’s visit to all the good, little boys and girls. The acquisition of the Dublin, Ireland-based cloud services company will give Bridgewater, New Jersey-based Synchronoss the ability to expand its global mobility platform enablement strategy considerably. The acquisition followed shortly on the heels of two C-level executive appointments at NewBay. The cloud services company appointed Tom Goguen as CEO in September and Mark Payne as CFO in October. Both were former RIM executives who now find themselves with brand new bosses. Still, this deal must have been in the works for some time.
