It’s no secret to anyone that the concept of SDN/ SD-WAN has been gaining ground over the past four years. This is in direct response to a clear need to erase geographical boundaries and improve visibility, control, availability, performance, scalability and security among others.
When I first laid my hands on a computer in the early Eighties, I didn’t realize at the time the full magnitude of what I was looking at. From then on, the interest in technology was never to end. Soon, personal computers (PC), with their colorful screens and countless possibilities, would start to be popularized among residential users and businesses starting to put their new equipment to work to improve productivity and unlock new possibilities.
The Spanish Private Security Act sets different corporate security degrees or levels. Level 1 has the lowest requirements, while Level 4 corresponds to businesses or locations considered critical from a security point of view. Starting at Level 2, having a connection to an alarm monitoring center is considered mandatory (this applies to both private residences and small businesses), but it is at Level 3 where legal requirements become far more stringent. This category is reserved to locations with moderate to high risk exposure (such as financial institutions, art galleries, antique shops, jewelries, gas stations, lottery outlets, casinos, gambling halls and other locations were cash is stored or handled).
The concept of reactive programming is currently thriving. It consists of dealing with asynchronous data flows called streams. One of the libraries to offer this concept is ReactiveX, which spans multiple programming languages and takes the best ideas from functional programming and the Observer and Iterator patterns.
The goal is to achieve an easily scalable responsive application.
2018 has shown us that many of the predictions made at the beginning of last year by relevant consultants and market analysts related to Cloud technology, SD-WAN, Artificial Intelligence (AI) and more, can be acknowledged today as correct predictions…. Indeed, we can also say that some predictions have been slightly slower than were expected and others have even gone beyond their initial expectations for 2018. The latter can definitely be said of SD-WAN.
