Time flies, especially when we’re talking about technology. Where I was involved in 2013 in an investigation into the status of IT professionals in relation to the new software defined technology, it is now a hot topic
.
In 2013 gave half of the 117 surveyed IT professionals to be able to form no opinion yet on software defined, because there is not enough information was available. Only 29 percent saw software defined as the future. Unfortunately, I also have the (still) does not have new figures, but one thing is certain: no lack of information anymore. Different opinions, perspectives and even definitions dominate the trade press. Software defined is therefore frequently discussed at the IT department
The job of the IT administrator
.
It strikes me that after two year still confusion about what software defined technology now is. The technology means that hardware and software are completely separate. A separate management layer over the hardware is not a software defined, even though some suppliers sometimes called something different. It is a fact that software defined traditional IT infrastructures on its head. And of course, this is accompanied by a variety of advantages and disadvantages. During workshops we organize at Telindus on this subject, it strikes me that there is often the same questions come up. And it’s interesting, almost all of them are related to the current job of the IT administrator. I put three in a row:
1. Do I need to be a programmer?
2. I need nothing more soon to know the bottom? In other words, can I throw all my accumulated knowledge overboard
3?. I later still have a job?
Infrastructure is programmable
With an infrastructure in which the software is dominant, it is understood that the box of the IT manager certainly will change. But if we look at one question, no, IT administrators do not have to be programmers. But you will need programmers. In practice, a programmer usually know little or nothing of IT infrastructures and the IT administrator anything about programming. An IT administrator so will never be as fast programming as a programmer. However, the whole area will be programmable. Configure happened often before in a cli (command line interface), and depending on the complexity could sometimes take up to several days. With software defined this is achieved at the touch of button because scripts are deployed automatically. The administrator is given the task to make the translation from the network to the commands, the programmer executes the commands.
Responsibility
The moment a software defined environment is implemented, it does not mean that nothing can go wrong. Because everything is included in scripts and policies reduces the risk of errors, but the consequences greater when things go wrong because the script does not work for example. At those moments, knowledge of basic infrastructure is essential.
You can compare it with a visit to the garage. Where before the hood was up, it creates a link to a plug under the dash. But to find the cause, is still required specific knowledge. Not everyone can be a car ‘read’. In the data center physical servers virtual and it is up to the administrator to change with it. This does not mean that knowledge must be thrown overboard, because you still have to know what you’re building: what’s under hood. After all, you’re responsible for it runs.
Change Functions
It is a logical question, whether there are job losses in the management department as a result of software defined. The management of the infrastructure is there in recent years not become easier. Many companies have to deal with different systems over the years, and next to each other to function. Each system has its own specific features which knowledge within the IT department is needed. Not so much job losses, but roles will change
As previously indicated.; it is still important to know how the underlying infrastructure works. This knowledge will have to stay there. To a lesser extent, the physical setup, but more in the translation how to make this work by programming or to work together with other components within the IT infrastructure.
more and more managers will find themselves in the future have to deal with applications, in place of the complex infrastructure. Software Defined ensures that the focus for IT departments more will be placed on demand management rather than technical management. The technical management will be increasingly outsourced and IT professionals can focus on the customer within the company. Jobs disappear not, but there is also a responsibility of the managers to continue to develop and grow themselves.
