Information is the ultimate competitive advantage. In 2018, many countries had laws enacted that specified the locality of consumer data. As a result, companies can be held liable if this data enters the public domain. Therefore, despite the best efforts of Microsoft Azure to put security measures in place, the need for low-cost onsite data protection for consumer data housed on an Azure Stack system is a topic of concern for customers seeking to implement Cisco’s Azure Stack solution.
Data protection responsibilities
Enterprise IT is being transformed as cloud providers mature. Cloud providers are now offering computing, storage, and application services with exceptional elasticity, scale, resiliency, and availability on a consumption-based economic model. However, the choice between public cloud and on-premises infrastructure is not a binary one. As some workloads shift to the cloud, enterprises are also seeking to transform their internal data centers and services into offerings that provide cloud-like scale, flexibility, resiliency, and operational methods, with similar positive economic outcomes. To this end, architects are augmenting or replacing traditional, proprietary, and single-purpose IT infrastructure and applications with software-defined services, distributed processing, big data applications, and hyperconverged architectures.
The Cisco® Integrated System for Microsoft® Azure Stack enables your organization to access the development tools, data repositories, and related Azure services needed to reinvent your applications and gain new information from your secured data. Azure Stack provides the same APIs and user interface as the Azure public cloud. An integrated system enables your team to save time building cloud-enabled applications, even when disconnected from Azure, and manage customer data while adhering to regulations related to data location and accessibility. Cisco’s infrastructure provides the main automation benefits of the Cisco Unified Computing System™ (Cisco UCS®) with leading Cisco Nexus® Family networking and data security technology, while helping ensure the highest-performing design to meet your future hybrid cloud growth requirements. Azure Stack opens the door to new hybrid cloud possibilities. When you use the Cisco Integrated System for Microsoft Azure Stack, you gain high-performance networking and industry-leading versatility for virtualized environments with Cisco Unified Fabric. You also automate infrastructure management with Cisco UCS Manager and help ensure consistency with policy-based management.
Data protection is essential for business continuity, protecting against human error, data corruption, ransomware, etc. Figure 1 shows the data protection responsibilities for an Azure Stack environment.
Azure Stack data protection responsibilities
Your IT department can set policies and purchase security tools, applications, and services to try to stop or limit the impact of malicious insiders, external hackers, and viruses and malware. Backup generators can keep the lights on should a power outage occur. In fact, all of these investments should be made and maintained regardless of the IT infrastructure on which your data resides or your organization’s cloud strategy.
Earthquakes, tornados, hurricanes, and other natural disasters are typically addressed by planning and testing the capability of remote locations to keep your operations going. Although relatively few organizations experience these disasters, some industries require a plan to be in place and systems tested. Human and programmatic errors are far more difficult to prevent.
Data protection—no matter where your data resides—is a real concern, including in Microsoft Azure Stack. While Microsoft supports the Azure Stack software and Cisco supports the hardware components, it is up to you to protect your data in Azure Stack.
The Cisco Integrated System for Microsoft Azure Stack solution enables your organization to access the development tools, data repositories, and related Azure services needed to reinvent your applications and gain new information from your secured data. Azure Stack provides the same APIs and user interface as the Azure public cloud. The integrated system enables your team to save time building cloud-enabled applications, even when disconnected from Azure, and manage customer data while adhering to regulations related to data location and accessibility. Cisco’s infrastructure provides the main automation benefits of Cisco UCS with leading Cisco Nexus Family networking and data security technology, while helping ensure the highest-performing design to meet your future hybrid cloud growth requirements.

The solution addresses some of today’s main industry trends and challenges (Figure 2):
Regulatory limits on data location
In an effort to safeguard consumer data, many governments have enacted strong statutes that define exactly what type of data can move to the cloud and what type of data must remain confined to your data center.
In May 2018, 28 European countries begin enforcing the Global Data Protection Regulation (GDPR), which governs the locality of consumer data and establishes specific data-management job functions that must be addressed by each company doing business in those countries. Companies in violation can be fined up to 4 percent of their global annual turnover. This regulation also governs any non-European company that transacts any business with the 28 nations. Thus, the impact of GDPR is felt globally.
Many individual countries and local government bodies are also enacting similar legislation that will affect a company’s ability to move data to and from any public cloud. IT departments must be mindful of these new data limits to avoid public ill will should consumer data enter the public domain.
Vertical industry sectors such as financial, medical, and government organizations face ethical issues and potential public outcry should their customers’ data enter the public realm. Exposed credit card data can cause an immediate negative impact on a company’s finances, and the news is filled with examples. Imagine a healthcare company’s embarrassment should patients’ medical histories become publicly available. Even worse, the safety of a nation could be jeopardized if a secure government database were compromised. The question is, though: How can you manipulate data that cannot leave your data center?
Customization: Enable existing traditional applications for the cloud
Many organizations still run applications that were developed years ago, before smartphones, tablets, and various remote data collection capabilities became available. In addition, as businesses expand into new markets, the challenge of localizing these applications for language, exchange rate, and traffic patterns is a constant worry.
Such applications reside within your data center and cannot be hosted on a public cloud. This lack of cloud capability also prevents these applications from being co-licensed by third parties, eliminating a potential new revenue stream. If you could redesign these applications to incorporate new data input devices rapidly and use development tools and data stores, what positive impact might this have on your income?
Connectivity issues: Latency
Some data center solutions and applications run in environments that are completely or intermittently disconnected from the Internet. Mining, offshore drilling, and shipping operations are examples of environments in which a constant connection to the Internet is not possible. Many government and other highly secure data centers do not permit any connection to the outside world, and often any equipment going into the data center, even a laptop, cannot be removed for any reason. Temporary “data centers” supporting the Olympic Games, auto races, music concerts, and other large events often must process data while operating offline. How can Azure services be accessible when the Internet itself is inaccessible?

The Cisco solution starts with rack-optimized Cisco UCS C240 M5 Rack Servers. These models house two Intel Xeon Scalable processors, up to 1.5 terabytes (TB) of memory, and up to 96 TB of storage. You can select from 14 different processors, provided that each server is configured with exactly the same processors, memory, and storage. The servers drive the Azure Stack software and house all of the virtual machines and data.
Each server is connected to two third-generation fabric interconnects, which house the Cisco UCS Manager software. The use of two fabric interconnects means that there is no single point of failure in the architecture. These fabric interconnects are connected to two Cisco Nexus 9000 Series Switches to enable connectivity to the data center’s border switches. Each switch and fabric interconnect maintains a copy of the other’s configuration to help enable easy replacement should replacement be required. Each server is configured with NVMe cache storage and 40 Gigabit Ethernet, which is managed by a Cisco Nexus 2000 Series Fabric Extender. The unified fabric that connects the system enables 40 Gigabit Ethernet traffic, which is a clear benefit as the system configuration grows over time.
Azure Stack installation services managed by Cisco Advanced Services are included (a typical installation takes only 3 days) within the solution configuration. We place the system components in your system rack, as we support your choice of system racks. You can configure any node increment from four up to the limit supported by Azure Stack.
Unique to Cisco is the capability to add server nodes to installed systems without the need for any professional services. You can purchase nodes when you want at the most affordable prices and have them in your data center either boxed and stored or in the system rack ready to be installed as your needs dictate. When you need another server, simply place the server in the rack, cable it, and power it on. Cisco UCS Manger will autodiscover the system node, assign the Azure Stack service profile to the server, and integrate it into the Cisco UCS cluster. This process typically requires only approximately 45 minutes. Then simply access the Azure Stack Admin Portal, select Scale Unit and Add-Node, and enter the server’s address. Azure Stack will then copy the infrastructure files to the new server and integrate the server into the cluster. The cluster will then begin to rebalance the workloads. Within approximately 90 minutes, the new node is ready to process data: only 2.5 hours from the time you open the box containing your new server.
Cisco Solutions Support is also bundled with all installed solutions. Solutions Support is the highest level of Cisco support and provides onsite repair up to 24 hours a day, 7 days a week, within 4 hours. In addition, your support calls are automatically routed to a team specially trained on Azure Stack. This team can also move a support call to the Microsoft Case Exchange system to enable Microsoft support engagement as needed. With this process, human error in reentering call details is avoided. The call flow would work in reverse should you elect to contact Microsoft support initially.
