How to Avoid Falling Through the Cloud

Undoubtedly, cloud computing is on the rise. Enterprises are adopting hybrid multi-cloud strategies to find a balance between what to keep on-premises (or in a data center) versus moving to the public cloud.   

Approximately 70% of enterprise applications have moved to the cloud. We are entering an era where centralized processing will be decentralized. Enterprises are adopting a hybrid model where some functions will run on edge nodes. Infrastructure is becoming highly distributed and dynamic in nature. Cloud infrastructure is consumed ‘as a Service’. You can take a third-party API along with compute, storage and networking resources from on-prem to any of the public clouds, stitch them together to make them appear seamless, and deploy it in the market. 

Despite all these developments, several myths remain about enterprises running the business in the cloud. Here is a look at three such myths. 

 

Myth 1: Cloud is more affordable than data centers 

 

It is true that due to its elastic nature, the cloud can be more cost-efficient. However, in order to fully benefit from those savings, a business may need to upgrade applications and its base computer infrastructure – all of which can be costly. Legacy applications do not seamlessly migrate over to the cloud. Applications need to be architected to be consumed ‘as-a-Service’ and deployed for global consumption. 

To gauge your total cost output, you need to consider your entire IT deployment in public, private and hybrid clouds. Some workloads and processes are more easily shifted to public cloud than others. And regulatory or business requirements may further complicate the financial aspects of cloud migration. Those factors can lead to the conclusion that sometimes leaving applications on-premises is the right decision. For many companies, colo is the new on-prem, as that option enables companies to keep their data on their own servers.  

Don’t fall through the cloud 

Then there are those poor companies that get sticker shock when they see the costs of cloud compute after a few months. To avoid falling through the cloud and plummeting into a land of unplanned expenses, companies must do the arithmetic required to analyze compute cycles, volume of data to be processed, data sizing, network bandwidth assessment, data egress and ingress locally and globally, as well as the geographic deployment of the applications and data at the edge. Using storage in the cloud may generate a huge bill – if not monitored properly.  

Consider licensing, for example. If you're migrating an application from the data center to the cloud, your operating system licenses probably won't transfer with it. It's great to be able to spin up a Linux server on AWS at the push of a button, but few take the time in advance to find out whether that action includes the hidden cost of having to pay for a license for the operating system on top of the cloud service fees. Even though you've already paid for that Linux license once, you may well find yourself paying for the same software again.  

Understand the fine print. Cloud service fees are rarely all-inclusive, as hidden fees lurk under almost every action you can take. If you spin up virtual servers for compute cycles and increase network bandwidth capacity for a given task, you must remember to tear down the services to avoid unwanted accrued bills. As far as software licensing goes, you might be able to save money by installing software you've already paid for on a cloud platform, rather than using the service's (admittedly more convenient) one-button install.  

When is cloud worth the cost? 

It may be worth an increase in cost to run workloads in the cloud if it enables the realization of a business goal. If business growth depends on the ability to scale up very rapidly, then even if cloud is more expensive than on-prem, it could be a business growth enabler and could be justified as an investment. We believe that the companies that do not exist today and will be created in next five years will be created on the cloud. It would be prudent for the new businesses to have a cloud presence along with their own footprint in the data centers. 

 

Myth 2: Cloud is more secure than data centers 

 

In the past, cloud computing was perceived as less secure than on-premises capabilities. However, security breaches in the public cloud are rare, and most breaches involve misconfiguration of the cloud service. Today, major cloud service providers invest significantly in security. But this doesn’t mean that security is guaranteed in the cloud. 

Data privacy and data protection policies remain a top concern on the public clouds. Due to the COVID-19 pandemic, videoconferencing applications have experienced a sudden surge. For example, a lot of people have been working from home, students have been using distance learning tools, and people have been using the same tools for group chats.  

You’ve probably heard that the Zoom videoconferencing service experienced a security breach where intruders hacked in and disrupted calls. Such incidents have been dubbed as ‘zoombombing’. Various similar incidents have been reported, including from classroom sessions and business calls, where intruders disrupted what was supposed to be a closed group call. 

Myth 3: Moving to the cloud means I don’t need a data center 
 

While cloud is highly suitable for some use cases, such as variable or unpredictable workloads or when self-service provisioning is key, not all applications and workloads are a good fit for cloud. For example, unless clear cost savings can be realized, moving a legacy application to a public cloud is generally not a good use case.  There are many different paths to the cloud, ranging from simple rehosting, typically via Infrastructure as a Service (IaaS) or Platform as a Service (PaaS), to a complete changeover, to an application implemented by a Software as a Service (SaaS) provider.  

To take advantage of cloud capabilities, it is essential to understand the model and have realistic expectations. Once a workload has been moved, the work is, in many ways, just beginning. Further refactoring or re-architecting is necessary to take advantage of the cloud. Ongoing cost and performance management will also be key for success. CIOs and IT leaders must be sure to include post-migration activities as part of the cloud implementation plan. 

The Power of a Strong Data Center Network Ecosystem

What should you look for in a strong network ecosystem? The most crucial aspect is that data center clients should be able to connect to cloud service providers (CSPs), their vendors and partners, and their own network assets through a private connection, without going over public Internet, on a global level.

According to a Gartner report “By 2022, 60% of enterprise IT infrastructures will focus on centers of data, rather than traditional data centers.”

We live in an ever-changing world of information technology that is impacting every aspect of our life. Gartner writes that infrastructures of the future will not be architected based on existing topologies, rather they will be deployed on a global scale, driven by business requirements and unspecific IT vendors. The end result will be an environment that is focused on enabling the rapid deployment of business services (by the business) and deploying workloads to the right locations, for the right reasons, at the right price. That means you need a data center that has a scalable infrastructure connected to a robust global ecosystem. 

Strong network fabrics connecting one data center to another -- locally, nationally or globally, enable you to connect your IT deployments across disparate data centers. These networks can be short-haul and cross a metropolitan area or long haul to connect across the country or even overseas. Whether you are planning a data center migration, disaster recovery or workload distribution, you need a strong network fabric to future-proof your IT strategy. Infrastructure must allow the enterprises to do what they need to do, when they need to do it, anywhere in the world. 

On the other hand, interconnection offers scalability and cost savings for the growing needs of enterprise customers. With an interconnection platform, retail and wholesale colocation environments can be connected to multiple cloud providers (multi-cloud) and multiple cloud locations (availability zones). This design opens the door to unique options for companies to architect their IT environments to optimize resiliency and availability while minimizing cost and complexity. Virtualization via Software-Defined Network (SDN), Network Function Virtualization (NFV) and Software-Defined WAN (SD-WAN) enables new services and capabilities to be created in minutes, not in days or weeks. The way Gartner says, we need to create an environment where the role of IT is to deliver the right service, at the right pace, from the right provider, at the right price. And data centers, as the hub of all things critical, become the critical delivery vehicle for these services. 

As an example of how important a strong data center ecosystem is, let’s take a look at Dallas, the #3 data center location in the world. Dallas is a destination market for data centers, meaning enterprises and cloud companies want to include Dallas as part of their global data center footprint. These companies need to distribute applications around the world for maximum performance and reliability. In a recent market report, Cushman & Wakefield ranked Dallas as #2 for global fiber connectivity, right behind Silicon Valley. 

For this strategy to work, a strong network ecosystem is key. Our Dallas TX1 Data Center is carrier neutral with a number of onsite carriers as well as dark fiber connections to the local carrier hotels, providing access to over 70 carriers and global interconnectivity.  For global, secure networks, our clients can use NTT’s Arcstar Universal One virtual private network (VPN), which offers high-quality, global network coverage in over 190 countries. In addition, TX1 is connected with our campuses in Sacramento, California; Ashburn, Virginia; and data center campuses under development in Hillsboro, Oregon; Silicon Valley; and Chicago, so workloads can be distributed, balanced and backed up across the country. Lastly, we offer secure, dedicated connections to the world’s largest cloud providers and a number of SaaS and content providers.

To sum up, it’s clear that the hybrid computing model combining data centers and clouds with a global, seamless, and secure network is the direction that corporate IT is heading. To support hybrid computing, data centers have evolved beyond space, power, telecommunications, and security. Data centers have become a critical infrastructure platform for both cloud providers and enterprises. And locations like Dallas have become integral parts of every data center’s network strategy.
