Cloud computing market: The next big Data center?

In the Cloud's it world, wonderful changes are unfolding, and each company can invoke all kinds of computing power indefinitely, using software, and then handing them over to the mighty ether (ether). For this vast and magical cloud power, companies only need to "how much, how much", not even to build, train and maintain.

As more and more services, companies, computer functions and malware removal software break into the cloud market, the entire market seems increasingly complex.

Amazon Elastic Computing Cloud EC2 is a typical case based on the IaaS (infrastructure as a service, infrastructure, services) platform. EC2 the surface looks like a rented data center, and indeed it does.

With IaaS, users can run programs on demand and freely adjust each data center tool, such as bandwidth, storage, memory, other servers, and security, because IaaS was designed to be an idealized data center, no longer the dusty satellite data center in the image, IT staff also do not need to be physically unwell to perform two disaster recovery training every year.

Essentially, the difference is that in the Amazon cloud, all hardware is automatically updated, all software can guarantee nearly 100% of the online operation, users do not worry about uptime. (EC2 still has downtime, Microsoft's Azure platform, Google's Gmail and other information management applications.) But customers do not have to worry about it, they can completely ignore the risk of downtime, even if the downtime really happened, they can complain, waiting for the program to recover. On the cloud platform, all problems are given to IT personnel. ）

Cloud service architecture is layered, regardless of cloud sparkle

So, "cloud" it architecture is surrounded by a circle of mysterious luster. But if you squint a little, you will see a "pyramid" hidden in the glittering mist and wind.

In general, because of too much hype, cloud computing market is shrouded in a thick fog, so that we can not see the real structure of cloud computing. You can only see the truth unless you are willing to risk the mist.

However, when you see clearly, you are disappointed. Because the cloud architecture looks so familiar.

Renting equipment without enough knowledge

The cloud looks like a complex OSI (Open Systems Interconnection) seven-layer network model, or a data center graph drawn by people with poor sense of space (they place the store at a distance of 100 miles from the transaction manager).

Interestingly, when you rent every level of functionality in your network and data center, you can choose from different vendors, regardless of their location.

Looking at the data center and the OSI diagram, you'll find that the bottom tier is the physical layer-the wire connecting your data center to the cloud Service data center.

You can rent them from telecoms operators, and the carrier's operating model is just the same as that of the cloud service provider, but it is only slightly underdeveloped. (in terms of telecommunications, "cloud" means "don't worry about any technical problems, just connect to the power and pay for it immediately, and we can help you achieve everything.") ）

Part of the deployment of the second tier (data link layer) requires you to do it yourself-pack your data to be accepted by other networks and applications. This is the only part of you that needs to be hands-on.

The third tier-switches and routers-also comes from telecom operators, as are the fourth layer (transport layer). (Essentially, the third and fourth layers are all transmissions, except that the fourth layer is slightly intelligent and the third tier needs to invest more in the hardware, so the third tier is a layer that the vendor attaches great importance to.) ）

The fifth layer, the session layer, is about cloud platform software. Cloud brokers build relationships between applications and databases, the connections between applications, and the connections between applications and networks. Cloud Brokers resolve their conflicts and, if necessary, disassociate them, and export them to the cloud at any time according to the needs of the end-user.

This layer contains IAAS services such as the Amazon Elastic Computing cloud. You can create value by free activity in the data center as needed. In the data center, however, the technology that should have been very simple was unexpectedly complicated and misery-oriented.

Importing an application to export a cloud platform is tricky, as is the case for cloud providers. Cloud Vendors Cram APIs (application programming interfaces), middleware, and information exchange technology into the entire box, like a shoebox filled with mice, where space utilization reaches its limit, and if a few more are put in, the original mouse will be hard to run.

However, cloud providers do not want you to see this. This may be a big dark side of cloud computing.
