2018 has seen the acceleration of modern infrastructure from public cloud, SaaS, hybrid, and SD-WAN. 2019 will see enterprises feeling the impact of this dramatic shift more than ever.

Internet unpredictability impacts become more visible as SD-WAN projects spread and mature
SD-WAN adoption is on the rise, and with it, the enterprise’s growing dependence on the Internet. Before moving to SD-WAN, most enterprises only had to worry about Internet performance from its data centers to key services. As a large number of enterprises move from deployment into their operations stage in 2019, the impact of Internet unpredictability will become more evident. As a result, more enterprise IT teams will start to develop operational capabilities to deal with Internet-centric issues.
Digital experience will confront the weight of backend multiplicity
Enterprises and SaaS providers are increasingly leveraging third-party APIs and cloud-services as part of their web and application architectures. Even a seemingly simple “Buy Now” function on an ecommerce site will invoke many external services, including payment gateways, CRM, analytics, inventory, fulfillment, and potentially many others.
The weight of all these external dependencies means that websites are going to continue to get slower, while at the same time their risk surface increases. Isolating the source of a problem when something goes wrong can be challenging, and the question of whether the application or the network is at fault will become “Which application?” and “Which network?”
Understanding the tradeoff of function over user experience and knowing how every third-party web or app component impacts performance will get even more critical to enterprises and SaaS providers in 2019.
Fragmentation, not bifurcation of the Internet
Eric Schmidt, former CEO of Google, famously predicted that the Internet would bifurcate into a US-led Internet and a Chinese-led Internet by 2028. Multiple nation states, including Iran, Turkey, Saudi Arabia, and Russia, have joined China in creating a walled-off Internet, using a variety of technical, social, and political techniques. As more countries pursue nationalist agendas and choose to opt out of regional or global alignments, we will see increasing Internet fragmentation. This will initially take the form of politically-motivated censorship but will expand to include the broader curation of connectivity based on politically-prescribed social and cultural norms.
Hybrid starts tilting to the cloud
While the data center will continue to lose ground in favor of cloud, enterprises still early in their cloud journey or who have special security or regulatory constraints will keep hybrid cloud alive.
2019 will see an increased tilting of hybrid towards public cloud providers, though a lack of maturity may cause an initial freezing of the hybrid market, particularly for AWS customers, who will want to consider an AWS offering over existing network providers once commercially available.
The Edge gets less “edgy”
Early edge architectures, where the data of billions of IoT devices is notionally processed at central points by infrastructure in public cloud or private data centers, presented challenges, ranging from security to physics (increased latency) to cost (bandwidth). The introduction of intermediary nodes into edge architectures will address the latency and security concerns of a strictly core/edge architecture, moving edge deployments in 2019 from largely theoretical to realizable.
Intermediary nodes are designed to perform some of the processing functions of the cloud closer to the edge, which will help extend the reach of cloud-centric infrastructure to the range of single digit milliseconds and make IoT and edge computing aspirations a reality.
Cyber attacks focus on foundational Internet systems for maximum effect
The pervasive risk associated with offering a digital service has forced most large enterprises and digital businesses to employ sophisticated systems of defense. Cyber attacks will continue to make headlines in 2019, but they will largely take an indirect approach, exploiting relational weaknesses in foundational Internet systems, such as DNS and BGP routing.
Indirect attacks, taking advantage of critical dependencies outside of the control of the intended target, will continue to grow in 2019, netting more high-profile victims while maximizing the scope of collateral damage.
The operational impact of cloud adoption pushes enterprises to reexamine their management stack mix
Now that SaaS has mainstreamed, with most enterprises shifting their application consumption model from internal to the cloud, we can expect to see a follow-on shift in IT operations stacks in the coming year, as more enterprises begin to realize that the existing toolset is not oriented to address externally-hosted applications.
Network tools that collect data from on-premises will see a reduction in usage and budget allocation, making room for cloud-specific technologies designed to provide visibility into networks and services that enterprises rely on (such as ISPs and SaaS apps) but that they do not own or control. This new operations stack will continue to feature traditional toolsets, but its proportional emphasis will favor cloud-focused technologies.
With many enterprises new to NaaS, service providers can differentiate themselves from competitors by prioritizing superior customer service and experiences.
Unlocking the full potential of telecom in the SaaS era relies on comprehensive strategies and a constant commitment to evolving security practices.
Eliminating complexity by standardizing with a platform approach is the way to put the brakes on the complexity cycle.
