Portability Goals Providing Location Adjacency When we talk with our customers, there are usually numer- ous organizational goals or incentives for portability. How- ever, they generally fall into a few basic categories. Cloud providers operate at different levels in different geographies. It is not unusual for an underserved company location to find that they only have one realistic cloud avail- able to them. By having the ability to move or replicate workloads across cloud provider platforms, it is often possi- ble to provide business capability closer to the point of need to address issues such as performance and availability. Avoiding Vendor Lock-In Most organizations try to keep their options open when it comes to suppliers, and the cloud is no different than some- thing as mundane as office supplies or janitorial services. Maintaining an available source of substitute (similar and readily consumable) capabilities with multiple cloud provid- ers theoretically increases one’s negotiating power with those providers. This economic principle of substitution is well understood by business leaders and is the major driv- ing force behind most multi-cloud strategies. Mitigating Risk Closely associated with avoiding lock-in is the desire to min- imize the risk associated with operating critical IT work- loads with a single provider. With every publicized account of a public cloud outage or other similar event, there is renewed interest in portability between vendors. In fact, even with a single vendor, this portability goal is desirable across multiple logical or physical locations. Satisfying Vendor Preference Organizations are increasingly finding that their customers and business partners have preferences when it comes to cloud vendors. The ability to provide application services across major cloud platforms makes it more likely you can serve users on their platform of choice, so you become more attractive to customers and business partners. This is especially true in situations where the customer or partner has a significant need to integrate with data or other appli- cations already present in a specific cloud platform. 64 | THE DOPPLER | WINTER 2019 Portability Challenges Although the industry has made it seem that cloud porta- bility is easy, there are some significant challenges to either overcome or accept. Security / Compliance Concerns The major cloud providers deliver solid coverage of the common compliance frameworks and standards. However, there are still variations in the types and levels of coverage among providers, and these differences are sometimes crit- ical when considering how to move workloads between pro- vider platforms. If a specific security or compliance control is not present in a provider platform, that could eliminate that platform from portability consideration unless an alter- native is found. Data Gravity Because portability is usually concerned with ensuring the movement of applications and data, having access to the appropriate data in all provider platforms is important. In environments with a significant amount of data, moving that data back and forth between provider platforms is often not desirable. And while it is usually technically possi- ble to access data in one provider platform from workloads located in another, there can be significant cost- and secu-
