The number of enterprise employees who work in remote offices and branch offices (ROBOs) continues to rise, and consequently, so do the amounts of business-critical information stored in these locations and IT budget dollars devoted to managing these systems. Yet one figure that is not going up is the small number of dedicated IT personnel available to staff ROBOs. This inevitably leads to poor system performance, unreliable data backups, and system outages that all directly impact employee productivity and the amount of time and money IT must devote to remediating issues. The solution is not to try to modernize the branch office IT infrastructure by purchasing and installing new, fancy equipment and resources, but instead to implement a Zero Branch IT model. This “software-defined edge” architecture consolidates ROBO IT operations to central data centers. Removing physical servers, storage, data and backup from ROBO locations enhances security, reduces operational costs, ensures reliable data backups, and increases overall business productivity by providing all users with the high levels of systems and applications performance that they expect and demand, when they require it.

ROBOs are business-critical
When Riverbed conducted a study of roughly 300 senior IT professionals for its Data center and Branch Office Resiliency Survey Report, a majority of respondents affirmed the continued, even increasing, importance of remote offices and sites. Among the most striking findings were the “three 50s”:
- Almost 50 percent of all employees work in remote sites
- 50 percent of companies’ data is stored outside the data center
- Branch offices represent roughly 50 percent of IT’s budget
These findings should come as little surprise when you consider that the average corporate data center serves 55 ROBO locations. This demands replacing the typical branch office IT infrastructure. Islands of distributed servers and storage deployed to meet local performance and reliability needs are insecure, costly, complex, and inefficient to manage.
Throwing money at the problem won’t work
As enterprises allocate more workers, data, and money to their ROBOs, IT’s focus over recent years has been on modernizing the data center. The Taneja Group reports over 25 percent of organizations it recently surveyed are looking to adopt hyper-convergence as their data center architecture. Many of the hyper-converged options on the market are beginning to offer small versions of their solutions for ROBOs. However, the typical hyper-converged appliance was designed as a piece of data center equipment, meant to simplify and scale data center infrastructures. It converges servers, storage, virtualization and networking into the building blocks of one system that, theoretically, would be easier to maintain and service than a collection of individual point solutions. And while this seems fairly straightforward, and may seem like a great idea for ROBOs, it is also important to recognize that the challenges IT organizations need to address in the data center are quite different as enterprises become more distributed. This forces IT to perform monitoring, maintenance, and troubleshooting remotely – site by site. But popular hyper-convergence appliances are not designed to be remotely managed en masse, don’t address unreliable networks and mass amounts of data over distance, and converge storage locally and directly within themselves – at the edge. This creates a number of data protection issues, and therefore, operational issues and cost to the business. Deploying new remote sites for a distributed organization is complex, expensive, and time-consuming. Every site requires dedicated hardware, software, licenses, and, quite often, at least one (sometimes more than one based on specialization) IT administrator. This makes it very hard for IT to quickly react when the business requires a change at one or more remote locations. The solution is not to invest more time and money in hardware at the ROBO. In fact, take just the opposite approach: create a software-defined edge model that removes stateful infrastructure from ROBOs, and at the same time, centralizes application delivery, data storage, backup, recovery and all other IT operations to the main data center.
Zero Branch IT
Today’s powerful smartphones and tablets are proof that the software-defined edge model works. Any app and information (e.g.: data) you want to access for work or play is available with just a few taps on the screen. Downloading and installing a new app happens almost instantly. Your data is secure in the cloud and available whenever you need it. If you lose your device, it’s easy to load that information onto a new device. IT can replicate that user experience for all frontline workers, reduce the costs and complexities of managing such a highly distributed environment, and without weakening the organization’s security posture by implementing a “Zero Branch IT” model. This enables IT to manage everything inside a secure, centralized datacenter or in the cloud and quickly deliver applications and data to users at ROBOs. The key benefits include:
- Hardened security posture: 100 percent of data is secured in the data center (also eliminating the need for remote backup processes), not sitting on a piece of hardware in a far-away ROBO location, out of your control; and without compromise to remote user productivity. All data is encrypted at rest and in-motion for true end-to-end encryption.
- Improved user productivity: Generate up to a 100x increase in remote application performance. Users will encounter far fewer instances of downtime due to system outages or poor performance. Ensuring information and system availability enables users to get their work done using any device they choose.
- Ensure business continuity: 100x faster recovery times (RTO) minimizes the business damage done by outages. Perform backup and recovery operations from a central location and in mere seconds instead of days or weeks.
- Improved operational agility: IT can deploy new branch services and sites in under 15 minutes, and manage everything via the central dashboard. All heavy ROBO IT operations, such as provisioning new services and sites, and recovery of sites in the case of outages, take seconds or minutes instead of days, weeks, or longer. Remote backup headaches are completely eliminated because data no longer lives at the edge. The result is a more agile IT team that is better able to support the always-changing needs of the business.
Modernize edge IT
Consolidating infrastructure at the edge is the critical first step. But it’s just the first step. Again, simply mashing together disparate pieces of hardware into one appliance will not solve short- or long-term performance, data security and management issues. You also need to make the edges “stateless.” If you’re a storage professional, you know “state” means facing daily operational challenges to manage and protect data at the ROBO that’s vulnerable to loss and theft. A lost storage piece at the ROBO will require hours, days, (or in some cases longer) of effort to bring it back online. And there’s no guarantee of success, particularly when resorting to older backups. Decoupling storage and compute, by moving data storage from the edges to the central data center creates stateless data stores, and in ideal scenarios, this can be done without compromising user experience. And since data assets are now centralized, the state remains only within the data center, where IT staff is readily available at all times, and the highest levels of protection exist. Today, it’s important for IT and Infrastructure architects and professionals to consider a new approach to remote IT by software-defining the edge. This enables IT organizations to centrally control the personality of every single location in the business no matter where they are. IT decides which applications, data, and services need to be available to workers at specific ROBOs, and when, in order to maintain the highest productivity levels and meet changing business requirements that allow enterprises and organizations to always stay at the top of their game: competitive and always focused on customer success.
