Container Technology Definition
Container technology is a solution to run a software application reliably when deployed in a different environment other than the one in which it was created. A lot of enterprises today have been facing challenges in running applications successfully, across varied computing environments. Not just the environment, but the network topology might also differ, or the storage might change. Such issues tend to make way for other problems like poor resource utilization and time consumption. Container technology provides an innovative solution to such issues and redefines how applications can be ported and be run in varied environments.
Containers have a runtime environment which contains the software application, dependencies, binaries, libraries, and configuration files. With container technology, the application runs on the container and thus, does not depend on the hosting environment, except for the operating system. A container can have several applications and each of them can have its own environment. If the container is installed in another environment, then the applications will all share the operating system.
With businesses consistently trying to minimize software issues, time-taken to fix them, and cost involved in the development of their products, the need for improved productivity and time to market for software products has increased. Container technology helps achieve these goals since it allows cross-environment compatibility, resource utilization, and eventually reduction in the overall time consumption.
Although more businesses have been embracing the technology lately, the security issues need to be addressed. It is believed that sharing of the operating system can lead to critical security threats. It is also said that container technology cannot provide the level of isolations hardware virtualization can offer. With numerous containers running a single application and hence, increase in the overall complexity, managing a large number of containers gets challenging in a production environment. Nevertheless, there is certain software already available in the market which addresses some of these issues. Being a relatively new technology in the market, container technology is sure to evolve with time and is here to stay.

Eliminating Application SDS Performance and Capacity Management Contortionism
White Paper By: FalconStor
With a good reason, Software-Defined Storage (SDS) has exploded into the storage market. SDS enables server-side storage (HDDs, SSDs, and storage systems) to be shared with multiple hosts and virtual machines. Application storage performance management is far too frequently a non-trivial operation. This whitepaper provides insights on ways to eliminate application SDS performance and...
