SD-WAN vs MPLS - It’s not either or!

There have been some misconceptions that SD-WAN and MPLS are mutually exclusive. In fact, they are quite complementary. While most SD-WAN deployments include active utilization of broadband services, many continue to utilize MPLS circuits as part of the WAN transport resource pool.
Enterprises with dual MPLS circuits at each branch site often allow one contract to expire and then continue with a hybrid strategy. We are beginning to see customers allow their secondary MPLS contracts to expire as they become comfortable moving forward with dual broadband services only. The result is tremendous bandwidth improvements and cost savings.
An intelligent SD-WAN platform can combine transport services into a single, logical high-bandwidth link, improving application performance. More advanced platforms continuously monitor the throughput, packet loss, latency and jitter of all transport services. The SD-WAN then automatically routes traffic – and when necessary, reroutes traffic – to maintain compliance with Quality of Service and security policies.

Can freelance engineers benefit your construction business in 2020?

As updates emerge of global talent gaps, freelancers can power growth in the people-intensive construction sector. Over the last couple of years, independent news and updates regarding talent shortages and a skills gap have been shared by various HR and talent management experts from the global business community, and the construction industry, in the Middle East and elsewhere, is no different – but freelance engineers may soon change these dynamics in the people-centric building sector. One of the most labour-intensive forms of economic activity, the construction industry is a major contributor to job creation and productivity. Given the fact that construction projects have a life span, the time that professionals spend with construction companies is, much like in the oil and gas industry, fixed for several years. However, with countries like the UAE rolling out long-term visas for specific groups of professionals, including investors, entrepreneurs, innovators, and talented experts

Advantages of the cloud service

The service provider takes care of everything : resource allocation, maintenance, improvements and updates ... Thus the owners of the service can delegate all these aspects and save the associated costs. Mobility and availability : The user benefits from the  continuous availability  of their data. Therefore, at any time or place you can access them only by having a computer connected to the Internet Savings : companies do not have to invest in buying and maintaining servers and software - With the cloud service a certain service is rented and paid for what is consumed. There are no Software licenses. Speed:  the cloud allows access to applications and services without having to download them, so companies gain speed in the implementation of projects. What allows us now the service in the cloud is precisely the separation between the programs that before we were forced to install and the operation of a certain tool. With this we manage to use applications or management systems remotel
