A year after raising $85 million from a group of high-profile venture capital firms and technology giants, Bracket Computing Inc. is adding an extra $45 million to its coffers following the completion of another investment led by an equally impressive roster of top banking institutions. The capital will help widen the adoption of its unique spin on containerization.

The concept of encapsulating applications in an interoperable package that can be easily moved among different kinds of infrastructure has gained a lot of steam recently among organizations hoping to exploit the the economies of public cloud for their traditional on-premise workloads. But the difficulty of bringing along the logical scaffolding that supports those workloads has proven a major obstacle to adoption.

That is largely due to the fact that most enterprise services are already encapsulated in virtual machines that are incompatible with mainstream containerization technologies, most notably Docker, which requires making major – and more importantly, costly – architectural changes in order to switch over. Bracket Computing offers a workaround.

Its namesake platform packages the entirely of an application, from the code and data down to the virtualization layer, into a so-called “Cell” that can seamlessly run on any of the major public clouds or even a combination thereof if necessary.  Bracket Computing claims that its technology handles all the logistics involved in supporting that arrangement, including provisioning and releasing resources, backup and security.

The startup places a particular emphasis on the latter, isolating the virtual machines in a Cell not only from the underlying cloud infrastructure but one another as well and providing integration with on-premise encryption appliances. That enables organizations to take extra security measures such as regularly refreshing cryptographic keys.

Bracket Computing’s security focus quickly caught the attention of the banking sector.  Private equity giant Blackstone Group LP was among the first adopters of its software, while Wells Fargo & Company accepted the team into its startup accelerator earlier this year. Now The Goldman Sachs Group, Inc. and Fidelity Investments are joining the fray as part of the new funding round.

Their participation not reflects their opinion on the revenue potential of Bracket Computing technology but also potentially its applications in their internal environments. The round brings the startup’s war chest to more than $130 million, which is quite a feat for a four-year-old startup was in stealth mode for the bulk of that time.
