Open Source In a Cloud Computing Environment.

Software pricing has always presented an issue for both vendors and customers alike. In the pre-Internet days software pricing on computer servers was roughly proportional to the cost of the hardware they were running on. In the days of mainframes and minicomputers this balance was fine but as the servers moved on from a lonely Intel box to a high-end cluster, things began to get complicated. It was quite possible that with expensive software such as well known database products, the massive price of software could limit the amount of money invested in hardware.

For example, Oracle’s database technology was specifically designed to run on inexpensive commodity servers (via Oracle’s RAC technology), with the idea that if the hardware costs are low, the overall ticket price is lower. This would be fine if all vendors stayed completely in step in terms of pricing policy. But that didn’t happen.

So the corporate technology buyers had a huge task on their hands in trying to build rational and reasonably priced business networks. Licensing is a potential nightmare that completely distorts the costs of purchasing software for business.

Once a vendor gets into a position of significant leverage, it tends to maintain the price of its product and seek to commoditise everything around it but the customer rarely sees any benefit from this.

This is one of the reasons that Open Source is important and why corporations really should take a punt and start using it. I’m not just talking Linux here, I mean the LAMP stack plus the JBOSS stack and a little bit of Open Office plus anything else that can deliver benefit. Oh and by the way, most open source software is good quality by the way.

Cloud Computing On The Horizon.

Open source software has been a viable option within the corporation, but it is now becoming a force of change. For better or worse, it is now part of the fabric of the IT industry. The area of the IT industry that was never been backward in adopting Open Source, and were instrumental in establishing it, are the xSPs, now referred to generally service providers. They have always been enthusiastic users of free software and web hosting companies seem to use almost nothing else.

Open Source imposes a constraining business model on anyone who wants to make a business out of selling the Open Source software. The GPL pretty much torpedoes any business model based on the direct software sales of the Open Source product. But the GPL doesn’t and cannot prevent people renting the software out, no matter whether the company doing the renting simply claims to be charging for support or claims to be offering Software As A Service (SaaS). When you buy SaaS you do not contract to use specific products, you simply contract to use an application or a set of applications – and, at the end of the day, applications are what IT is about.

If you use Salesforce.com for example, you may well use software written by the company itself, but it is possible that you’ll also be using some software provided by their partners plus Open Source products. You just won’t know and you won’t care either. You’ll only care if the software fails to deliver the contracted service in any way. There are no simple and generally agreed models for pricing SaaS, primarily because its major competition is not other SaaS. Its major competition is in-house software and it only has to cost less than that, and be reasonably easy to implement, in order to establish a market.

The costs of cloud computing network services will follow a similar model to licensed software because as the cloud business grows it will need to invest more in the platform. Open Source is particularly appealing to SaaS vendors, because its costs flat-line as the business continues to grow.

As software moves towards a different model, the market impact of the Open Source GPL will diminish on one side of the equation, because it will become easier to exploit commercially. However, it will also force it competition into a difficult position – because their costs don’t flat-line. The natural impact of this will be to encourage proprietary software products to establish a SaaS market as quickly as they can – before it gets taken by an Open Source option. If an open source option gets established it will be difficult to compete with.

A guide to Cisco certification

Network security is one of the most crucial parts of being an IT engineer. A  network administrator should be capable of implementing and maintaining security solutions on a client network. A network security professional is one who develops business solutions, and one who monitors, designs and implements network security from all levels. Among the wide array world-recognized technical certifications issued by Cisco Systems, Incorporated is the professional and expert level of security certification.

Firstly, there is Cisco Certified Security Professional. A CCSP certified individual has an advanced knowledge when it comes to the technology implemented and the Cisco products used to provide security solutions on networks from all levels.

To be a CCSP, an IT professional should first pass either the Cisco Certified Network Professional or the Cisco Certified Internetwork Professional examination.  Next,  there is an expert level of security certifications issued by Cisco, this is called the Cisco Certified Internetwork Expert. For this expert level of certification an IT professional can take an examination for different fields of specialization such as routing and switching, security, service provider, voice technology and storage networking.

The Cisco Security Examination”

To achieve a CCSP or a CCIE Security certification, an IT professional needs to sit a written and a laboratory exam. This exam is made up of multiple choice questions about security protocols, application protocols, general networking, security technologies, Cisco security applications, network security in general and general Cisco security information.

To achieve a CCSP certification, a candidate must pass a two-hour qualifying exam. The aforementioned topics are covered, which will mainly include networking concepts as well as equipment commands. Once the candidate passes the written Cisco Security exam that is when the candidate will be eligible to take the lab exam.  After the candidate has passed the two hour written qualifying exam, the next step is to undergo the CCIE security laboratory examination. This exam is tough and has eight-hour duration. The main purpose is to test the candidate’s ability to get a secure network running at a particular time.

Before  taking the Cisco security examination, either for the professional or the expert level, a candidate should undergo several security trainings. This includes the Cisco security training as well as the Cisco Secure SAFE Implementation. The Cisco Secure SAFE Implementation is laboratory intensive, which will help a candidate successfully pass the laboratory part of the Cisco Security examination.  Be it an examination for the professional or expert level of the Cisco Security certification examination, a candidate needs enough preparation to pass the written and laboratory tests. This way, the IT professional will have sufficient knowledge about the specific Cisco security protocols and components, to protect the entire network.
