Network Design and Management Trends

Virtualization

            In 2016, virtualization for the second year in row was among most searched topic on Google. The popularity can be attributed to meteoric rise of container related services such as Docker and continued increase in popularity in cloud platforms. In 2015, virtualization also was on top of the chart as one of the technologies to watch. A closer look of the technologies that enhance virtualization can aid in understanding of the increased popularity of the technology(Yamanaka, Kawai & Shimojo, 2016). Network Design and Management

            Docker and VMWare.Discussion about hypervisors and containers was constantly high in 2016; the discussion intensified when Docker partnered with, Google, Red Hat, canonical, parallels, and Microsoft in 2015. The partnership evoked a lot of debate with some people arguing that the time of Hypervisors is over and that of containers has begun. Some people are also of the view that hypervisors are going nowhere(Yamanaka, Kawai & Shimojo, 2016).

            It is true that Containers are light and VMs are heavy, and the technology horse race between Containers and VMwares puts both of the tools at odds with each another. However, the technologies are varying tools, which can complement or supplement each other provided they are used for the correct task. The debate between these tools has tremendously increased the popularity of virtualization from the beginning of 2014 until the end of 2015(Bianco, Bestak & Norros, 2016).

            Hybrid Cloud Strategies. In 2015, RightScale a hybrid cloud company reported that eighty-two percent of businesses have a hybrid cloud, which was an improvement from seventy-four percent in 2014. Cloud hybridization trends are attributable to the fact that virtualization only cannot make a cloud. According to the RightScale director, virtualization is only a foundation for cloud and hence cloud hybridization is required to create a complete functional cloud(“Application Aware Routing in SDN”, 2015).

            Some of the of hybrid cloud strategies include the ability to keep critical resources such as user files and details in a private cloud, utilize the public cloud for less critical functions, or  combine both of the capabilities. The hybrid cloud approaches depend on the user requirements for compliance, in-house team, security, and budget. According to lief Morin, any cloud solution adopted by an organization demands the information technology team to proceed with the cloud education, hence in 2016, IT professionals had to continue with cloud training and searching for information related to the technology(Yamanaka, Kawai & Shimojo, 2016). Network Design and Management

            Storage Virtualization. The purpose of storage virtualization is to create large pool of resources that are accessible by the end users on-demand. Heavy lifting in the background without the users’ knowledge is enhanced by the technology due to the existence of numerous physical storage spread across a vast geographical area. Changes in hardware created a need for the shift of professional roles, for instance the network administration is gradually shifting to data management hence creating a need for training. The training includes information about virtualization hence increasing the popularity of the subject on search engines(Yamanaka, Kawai & Shimojo, 2016).

            The increase in demand for hybrid cloud technology and other related tools from 2015 to 2016 account for the improved popularity of virtualization, which is the foundation for cloud, from 2014. Therefore, it can be assumed that people looking for information about cloud technology tools such as VMware, Dockers, and Hybrid cloud technology also searched for virtualization. Since companies, which have adopted cloud strategies require that their IT professionals continue looking for more information about the technology, it is clear that these people searched for virtualization hence increasing its popularity from 2014 to 2016(Yamanaka, Kawai & Shimojo, 2016).

            The interest by region map on virtualization (See the appendices section) shows that virtualization was most popular in India followed by USA. The interest in virtualization by both of the countries can be explained by the fact thatIT companies from USA market and outsource skills from India. USA having been with cloud computing for a while now, their focus is gradually shifting to other fields while in India the topic is still hot. Virtualization lags behind compared to SDN and wireless network because the technology has been around for a while and people have shifted focus to other emerging cloud related technologies(A.P & Sakthivel, 2015). Network Design and Management

Wireless Networks

            Wireless LAN (WLAN). In 2016, there was a continuous flow of WLAN (wireless local area network) developments, which made the subject trend almost throughout the year. For instance, MIT researchers released a technology for indoor positioning of Wi-Fi, which enabled access point to spot individuals within a distance of inches of their locations, which is a potential milestone for small businesses that cannot afford the-location based services. Cisco also unveiled a unique multigigabit switch hosted on cloud and increased desk phones and access points for Meraki wireless unit. Such development and many other led to an increased public curiosity that resulted to an increase in number of google queries hence made the topic to trend through-out the year. Notably the release of the wireless LAN products has been constant since 2014 hence creating a constant popularity of the mobile networks(A.P & Sakthivel, 2015).

            Mobiles Networks. The year 2016 also recorded some activities about mobile networking especially the 5G technology. The 2016 summer experienced a focus on the new 5G technology whereby AT&T using a different approach compared to Verizon in the next-gen cellular service. Aruba, which is a business on Hewlett Packard Enterprise (HPE) Company created a new and the first mobile platform that is based on application programming interfaces from a combination of six network products. The interest on the mobile networks has been increasing from 2014 to 2016(A.P & Sakthivel, 2015).

            Operating Systems. The introduction of mobile phones with sophisticated operating systems created a lot of interest about wireless network. One such development is the release of Microsoft windows phones. The windows smartphone wasreleased in 2011 following a partnership between Microsoft and Nokia. In 2014, Microsoft Corporation acquired Nokia and increased production of the smartphones. The release of the windows increased the popularity of the wireless network(A.P & Sakthivel, 2015).

            From interest by region, map (see the appendices) the interest of the wireless was at a 100 high since 2014 when the windows phone was released. Most of the keywords and phrases searched are related to the windows phone. The high popularity of the wireless network in china can be attributed to the robust mobile phones industry in china and the fact that the Microsoftwindow is not so popular in china. The wireless network popularity in the comparison graph is between SDN and virtualization. The technology has maintained almost a constant popularity even when there are no new operating systems being released due to the emerging developments such as the ones discussed above(“Application Aware Routing in SDN”, 2015).

Software Defined Networks (SDN)

            Software Defined Wide Area Network (SDWAN). SDN is finding a lot of applicability in wide area networks where the technology is used to minimize latency. Prior to SDN technology invention Network Architects were facing many challenges in connecting remote sites while utilizing few number of connectivity choices. Limited choices always led to bottlenecks, connections because of sparked outages, and increased latency. Existing WAN technologies were not adequate to solve the issue due to lack of end-to-end visibility. SD-WAN solved the issue by centralizing the control pane of the WAN hence enabledchoosing of the most optimal routes possible(A.P & Sakthivel, 2015).

            Software Defined Local Area Network (SDLAN). SDN is also creating a lot of interest as regards applicability to the local area network whereby the technology is expected to create many improvements. SDN is expected to enhance a complete end-to-end LAN with automated intelligence for provisioning and routing. The increase in demand of the SDN in the local area networks has also played a very big role in the increased popularity of the software-definednetwork, which translate to increased searches on google(Yamanaka, Kawai & Shimojo, 2016).

Data Center. The data center is another area where massive deployment of SDN components is taking place whereby the technology assists in eliminating the need for manual provisioning of new applications, services and other network functions. SDN also assists in ensuring that data flows can be automated at a granularity level unseen before. Applicability of SDN in the Data center since 2014 is also a very big contributor to the popularity of the technology(Yamanaka, Kawai & Shimojo, 2016).

            The increased in popularity of SDN is attributable to the increase in applicability in data center, LAN, and WAN. From the interest by region (see the appendices), SDN is most searched in USA reason being that the technology is new hence not popular in other areas. United States also has vast computer coverage involving various WANs and millions of LANs, hence explain the interest of the technology in the region. The comparison graph (see the appendices) shows that the most popular networking technology is SDN. SDN popularity can be attributed to its ability to solve various network problems and the fact that it is new hence creating a lot interest from people who need information about the technology.

Past Trends in Networking

Computer networking technologies in the past focused on the hardware, software, and networking speed. Many innovations were made regarding networking hardware such as cables, servers, routers, switches among others(Yamanaka, Kawai & Shimojo, 2016).

. The focus of most of the hardware such as fiber optic cables was to increase speed and the size of data communicated. Software and hardware mostly focused on protocols, routing and switching. Computer hardware companies had a booming business whereby it came up with sophisticated devices such as servers, routers, and switching (A.P & Sakthivel, 2015).

Modern Trends in Networking       

From the above analysis of network trends for the past three years shows the modern trends in networking are focusing on the software, code, and open systems. The report shows that virtualization, a cloud computing technology, was very popular for the past three years with technologies such as containers and hypervisors being hot topics over the duration. Storage virtualization has also been popular for a while now.

            Cloud technologies such as hybridization are also becoming popular topics in computer networking today. Most of services previously performed on-site such as security are currently possible on cloud through technologies such as software-as-a-service, in the modern world(A.P & Sakthivel, 2015). While software for cloud technology is reducing in size hence requiring no improvement in hardware it is also becoming extremely sophisticated. SDN is also increasing in popularity in the modern world where it is applicable in both LANs and WANs. SDN, which is basically a technology based on network software is highly improving networking whether LANs and WANs(A.P & Sakthivel, 2015).

            Currently the world is also moving towards a sophisticated internet of things where almost every electronic device on earth will be connected to a large network. In the report, it is evident that this topic is trending currently whereby Wi-Fi which can recognize the presence of people by MIT. From the technologies discussed above it is clear that modern networking has become a large open system.
