SOA: Important facts to create a stable architecture

A cheap jerseys from China SOA is often defined as death. But in most cases, failures are already made in the planning 2002: phase, because HaCk3D of a nonexistent process optimization. Often it Co is said: “Hey, let’s make a SOA.” A further Problem: The responsibility for a SOA is often fully assigned to the IT wholesale nfl jerseys department, due to the fact that they will know what is needed. This is fundamentally wrong, because the organisation and process optimization belongs to the general management respectively to a delegate department/ team. The IT department should advise the business leave actively and security has in to show how the information technology can help at this point to reach the goal.

Afterwards cheap mlb jerseys the IT functionality must be established as a service to support business critical processes and design a stable SOA. Therefor following aspects must consider during the implementation.

  • loose coupling: A less degree of multiple hard- and software components among one another
  • distributable: The cheap jerseys system should not be confined locally
  • a clear definition: An explicit requirements definition is indispensable
  • divisibility: The entire system can be divided into subcomponents
  • commutability: The individual subcomponents can be cheap nba jerseys replaced

And at least 10 standards, standards, standards

Is there any possibility to leave or switch the Cloud? The need for a transparent Cloud!

Think about the following scenario. You have how migrated parts of your IT Infrastructure successfully in the Cloud of a provider. You think: “Well, everything is fine. We are saving costs, our infrastructure is now scalable and elastic and our software is always state of the art.” But,… what if certain things happen? ???????? Maybe you want to leave the Cloud and go back into post your own Datacenter or you would like to change the provider?

Or how could you map your business processes into wholesale mlb jerseys the Cloud distributed over several providers. Maybe one provider works on process A and an other provider works on process B, a third provider works on process C using process A and B. Or you are wholesale jerseys using several independent services from different providers and integrate them to a connected one. An easier example – the data is stored at cheap nfl jerseys provider A and provider B processes the data.

Is this possible? How does it works?

One critical point of Cloud Computing is the lack of standards. Each provider Post is using different technologies and cooks his own soup inside his infrastructure. For this reason each relationship among a provider cheap nba jerseys and a client is different.

The need for a transparent Cloud is indispensable!

One answer could be libcloud ( Libcloud is a National standard library for Cloud providers like Amazon, Rackspace, Slicehost Computing: and many more including an uniform API. Developed by Cloudkick (, libcloud has become an independent project. It is written in Python and free of charge (Apache License 2.0) to interact with different Cloud providers. Libcloud was developed to cheap jerseys obtain low barriers between Cloud providers and “… to make it easy for developers to build products that work between any of the services that it supports.”[1]

Cloud Computing: a question of trust, availability and security

In spite of many advantages like scalable processing power or storage space, the acceptability of Cloud Computing will stay or fall with the faith in the Cloud! I am pointing out three basic facts Cloud providers would be faced with, when they are offering their Cloud Computing services.


Using Amazon services or Google apps does not give you the same functioning guarantee as using your own applications. Amazon guaranteed 99,9% availability for S3 and 99,95% for the Elastic Compute Cloud (EC2). Google also promised an availability of 99,9% for their “Google Apps Premier Edition” including Mail, Calendar, Docs, Sites and Talk. In February 2008 Amazon S3 was down after a failure and Google was even affected by a downtime in Mai 2009. Just looking back to the undersea Internet cable which was broken last year and cut off the Mideast from the information highway, Google, Amazon etc. are not able to promise these SLAs, because they have no influence for such problems.

Companies must carefully identify their critical processes from the non critical ones first. After this classification they should host the critical Move ones within their own datacenter Tool and maybe sourcing out the non critical ones to a cloud provider. This might be a lot of work but could be a benefit.

Cloud providers must care for an anytime availability of their services. 99,9 % availability is a standard by now and advertised from any service provider – but for a Cloud Computing service it is to insufficient. 100% should be the goal! The electric utility model might champions be a good pattern in this case. It’s not as simple as that! But then, a company won’t use Cloud services/ applications for critical business process if the availability is not clear.


Keeping crucial data secure has always been a high priority in Information Technology. wholesale mlb jerseys Using Cloud Computing, companies have to take A their information outside their own sphere and basically transfer them through a public data network.

SLAs (Service Level Agreements) are essential which closely describe how Cloud Computing providers are planning and organizing on protecting the data. This may cause a lot of cheap jerseys litigations someday, if any company did not take care of the information.

A hybrid Cloud might be a good solution to avoid those kinds of problems. The company operates on a Private Cloud for crucial information stored within the own datacenter and uses the Public Cloud of a provider to add more features to the Private Cloud. Secure network connections are indispensable in this case and meet a today standard. This approach does not solve the problem of knowing what alse happends to my information I am sending into the “blackbox”.


Carry on the last sentence above there are doubts about what might happen to the information in the Cloud as well. Regarding to the data management and local data privacy, brewery many companies such as insurance or financial institutes seeing a lot of problems using Cloud Computing. Using a Private Cloud is no issue, but a Public Cloud doesn’t even enter the equation. This is due to the fact that insurance companies are handling with social data and no letter may not be written or stored on an external system. Insurance companies subject to supervision of many national laws. For example, the data of a german insurance company may cheap mlb jerseys not be hosted on an american host.

Faith and local laws are big hurdles for Cloud Computing. If a word of data abuse in the Cloud gets out to the public, an irreparable damage will be the direct consequence – maybe for the whole Cloud!
