The annual virtualization confab will feature many of IT trends for 2018—containers, 5G and edge computing— that are critical for IT managers to consider.
It’s been said that IT infrastructure isn’t sexy anymore. Many in the technology industry now regard the application layer as the hotspot for innovation and agility.
But over the past several years, IT infrastructure has helped drive important advances in IT speed, agility, security and innovation. With new capabilities like networking virtualization and networking programmability, 5G technology and edge computing, as well as other new trends, IT infrastructure has earned back some of its lost mojo.
At VMworld 2018, the focus will be on how new infrastructure technologies have enabled business processes and innovation—and some of the developments yet to come as these technologies mature.
While most IT organizations have virtualized their server infrastructure to enable rapid change, better server utilization and cloud architecture, many still need to take virtualization to the next level. Server virtualization entails virtualizing hardware into software—known as virtual machines (VMs). These VMs mimic the functionality of hardware, while enabling better resource utilization, with many VMs dedicated to one physical server.
Still, while many companies have begun the server virtualization journey, they haven’t exploited virtual infrastructure to its full potential. They could attain further benefits through greater consolidation and other steps.
For example, most companies can further maximize virtual infrastructure by taking these steps:
Just as software-defined storage makes virtualized storage more mature, software-defined networking brings virtualized networks to a whole new level. SDN shifts capabilities from hardware to software. As a result, networking engineers can direct and manage traffic from a centralized control console via software without having to configure individual hardware components and without having to worry about the specific devices that components are connected to. In a cloud- and Internet-of-Things- (IoT-) driven world, this newfound flexibility and speed makes IT far more responsive to business needs.
Here are some reasons that many companies are now considering SDN:
With malicious hacking and security compromises becoming commonplace, smart IT organizations know that they must strengthen their security posture. One of the best ways to bolster network security is through microsegmentation and network functions virtualization (NFV), made possible through SDN. As part of implementing microsegmentation IT organizations spend time analyzing the traffic flows between critical applications as well as in and out of the data center. Once traffic is understood, microsegmentation allows you to create security policies down to the application level. As a result, a company’s network and critical data can be far more secure.
With NFV, IT teams can quickly and easily deploy software-based firewalls and load balancers when new applications are deployed. What this means is that firewalls can be deployed as needed to protect all applications. Also, load balancers can be put in place automatically with new applications to ensure quality of service for end users and to guard against denial of service attacks.
As more companies modernize their applications for the cloud, mobility and IoT, they are looking to run those applications in lightweight containers that are orchestrated by solutions such as Kubernetes, an open source container technology that enables development, management and deployment of applications in isolated environments. Well-orchestrated containerized applications provide IT organizations the scalability, availability and application portability that agile companies need. Of great interest for VMworld 2018 attendees will be how to migrate applications to containers and how to run containers (and container orchestration) on existing virtualized infrastructure.
As applications are modernized, IT organizations are considering edge computing as a solution for applications that process real-time data. By moving data processing for specific applications to the edge, closer to where the applications, devices and users reside, companies can reduce network traffic and costs while increasing application performance. VMworld 2018 attendees will be interested to learn how to deploy edge computing while still maintaining the management, security and compliance systems that they already have in place.
The long-awaited 5G wireless is coming soon, and it will bring faster mobile bandwidth and greater device access—without compromising security. For example, initial tests and predictions of 5G wireless speeds provide between 500Mb/sec and 1Gb/sec bandwidth at low latency. With this type of throughput, companies and consumers alike will find incredible new uses for mobile networks such as remote surgery, self-driving cars, real-time drone feeds, virtual reality, and faster, more secure home-bandwidth options.
Finally, IT organizations are migrating to the cloud where it makes financial or business sense. Common use cases for are cloud-based data protection/disaster recovery, web-facing applications, highly-elastic workloads and cloud-native applications.
It’s also important to note that migrating to the cloud involves hybrid cloud strategies, with some data and applications continuing to reside on-premises in a company’s data center, some in public clouds, and increasingly, some at the edge. IT organizations must continually weigh the benefits of public cloud as compared to on-premises alternatives.
All this points to several key IT trends moving front and center at this year’s VMworld. These trends are the backbone of all the application and device capabilities enterprises will need in the coming years—whether to promote intelligence and real-time collaboration among teams, to provide greater mobility and insight at the edge without the latency of going to the cloud or to promote new business capabilities through connected devices.
All of this technology will be on display at VMworld 2018, including benefits and ongoing challenges. If you’re a networking engineer or infrastructure architect, these IT trends are no doubt top of mind for you. See you there!
