How clouds change data centers

    Today, almost every third adult is connected in one way or another to the clouds. Our Gmail is synchronized with a smartphone, well, or the photos are uploaded to Dropbox, available 24 hours a day. It’s not for me to tell that in modern society, both large and small companies do not lag behind users and actively “go to the clouds”. Meanwhile, cloud technologies are being rebuilt and becoming more sophisticated and widespread, and these are not just words, but there are many facts that have already been repeatedly discussed by the Habra community. At the moment, as the development trend shows, the emphasis on data delivery, stability, and traffic distribution has begun to increase. Data centers, like other technologies, had to adapt to growing demands and trends by introducing new technologies.

    Cloud computing. As you know, there are four cloud computing deployment models — private, public, public, and hybrid clouds. Open source projects such as Open Stack and Cloud Stack create powerful cloud-based API models for implementing various services and platforms. Most of these technologies continue to evolve and improve. Cloud computing and related technologies unify cloud architecture. Software-defined technology today is more than just a big word. This is the way to organize the management of heterogeneous storage equipment at the same logical level. When a rapprochement occurs between the network, storage and computing on the one hand and software-defined technologies on the other, valuable “building blocks” for cloud data centers appear.

    Network communications.Cloud providers are deploying ultra-smart switching components that can handle thousands of virtual connections. Controls can bypass geographic policies and query rules. SDN (Software-defined Networking) allows you to create a global smart environment. It is planned that in the future SDN will create more flexible automation of traffic flows. IT administrators can use the management console without manually configuring the equipment. SDN can also provide resistance to DDoS attacks. You can also create a tunnel with data encryption, even if an attacker steals data, he will not be able to read them. Now SDN helps manage global traffic by logically directing it to the necessary data center. These achievements will help to cope with downtime,

    Overcoming the consequences of accidents / Continuity of production. Emergencies can occur at any time, and for any reason. Clouds will help in this case. Whether it’s an active site or a “pay-as-you-go” service, the disaster recovery strategy becomes more accessible. GSLB (global server load balancing) and GTM (global traffic management) technologies, as well as administrators, help users stay closer to their data centers. They distribute requests and loads on applications based on the user's location, server location, specific rules. As a result, the user connects to the nearest possible resource. Even if the connection fails, GSLB and GTM will immediately redirect the user to the next available resource.

    According to the latest Cisco Global Cloud Index:

    • The annual global cloud IP traffic will reach 5.3 zettabytes by the end of 2017. By 2017, global cloud IP traffic will reach 443 exabytes per month (compared to 98 exabytes per month in 2012).
    • Global cloud IP traffic will increase by almost 4.5 times over the next 5 years. In general, cloud IP traffic will grow by an average of 35 percent from 2012 to 2017.
    • Until 2017, cloud traffic will account for more than two-thirds of the total data center traffic.

    More data is stored in the clouds and devices are connected to the Internet. Projects can provide the user with their services and applications, without the availability of their own hardware. The reliability of computer computing is growing, which will help in the future to create new platforms and products.
