What Cloud Storage Standards Could Mean For You

Standardized access is one of many considerations when deploying cloud storage

The notion of standardizing access to object-based cloud storage across vendors and cloud providers is not new but promises to have a positive impact on cloud storage users and overall adoption. In his recent article, A Call for More Cloud Storage Standards Support, Mike Vizard calls for IT organizations to help hasten vendors toward compliance with the CDMI standards currently in draft.

The benefits of standards compliance are tangible, alleviating vendor lock-in due to proprietary cloud storage interfaces and enabling tighter integration of cloud storage with applications and operating systems, all while maintaining a choice of cloud vendors. What this translates to is customer “freedom of mobility” between different public and private cloud providers and investment protection for infrastructure or solutions that depend on cloud storage.

With standards still in progress, many cloud storage customers have discovered cloud storage mobility and freedom through cloud storage gateways, like CloudArray. These gateways eliminate vendor lock-in by using already standardized storage protocols, such as iSCSI, offering compatibility with the vast majority of operating systems and applications presently in use. Gateways make cloud storage compliant with today’s standards and bypass vendor lock-in concerns. Does this mean that gateways deem CDMI unnecessary? Not for every case. Customers unwilling to trade object-based interfaces for today’s standard block or file interfaces would still make a valid case for the CDMI standard.

On the other hand, consider that gateways provide a number of additional benefits that standards will not address, particularly when augmenting on-premise storage environments with cloud storage. These include:

  • Local caching and optimized cloud layout to improve performance. See John Bates’s write-ups on how gateways can vastly improve cloud storage performance here and here
  • Data reduction to reduce the amount of data stored in the cloud by eliminating duplicate data
  • At-rest encryption to ensure all data leaving the on-premise environment is fully secure
  • Improved data mobility using “cloud to cloud” migration rather than inefficiently moving data between providers via an on-premise hop

These features, along with others, are highly desirable with or without cloud standards in place. Even customers preferring to use object-based interfaces to cloud storage may choose to utilize a gateway that offers access via the CDMI standard to enjoy these added benefits – perhaps a roadmap item for future gateways.

While cloud standards promise native cloud storage compatibility, gateways provide an easy and practical entry to cloud storage today, offering cloud provider interoperability and a wealth of benefits that will continue long after standards are approved.

Transformation Abstract Encryption and privacy in the cloud is a daunting yet essential task for both security practitioners and application developers, especially as applications continue moving to the cloud at an exponential rate. What are some best practices and processes for enterprises to follow that balance both security and ease of use requirements? What technologies are available to empower enterprises with code, data and key protection from cloud providers, system administrators, insiders, government compulsion, and network hackers? Join Ambuj Kumar (CEO, Fortanix) to discuss best practices and technologies for enterprises to securely transition to a multi-cloud hybrid world.
"Calligo is a cloud service provider with data privacy at the heart of what we do. We are a typical Infrastructure as a Service cloud provider but it's been designed around data privacy," explained Julian Box, CEO and co-founder of Calligo, in this SYS-CON.tv interview at 21st Cloud Expo, held Oct 31 – Nov 2, 2017, at the Santa Clara Convention Center in Santa Clara, CA.
We are seeing a major migration of enterprises applications to the cloud. As cloud and business use of real time applications accelerate, legacy networks are no longer able to architecturally support cloud adoption and deliver the performance and security required by highly distributed enterprises. These outdated solutions have become more costly and complicated to implement, install, manage, and maintain.SD-WAN offers unlimited capabilities for accessing the benefits of the cloud and Internet. SD-WAN helps enterprises to take advantage of the exploding landscape of cloud applications and services, due to its unique capability to support all things cloud related.
Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
Containers and Kubernetes allow for code portability across on-premise VMs, bare metal, or multiple cloud provider environments. Yet, despite this portability promise, developers may include configuration and application definitions that constrain or even eliminate application portability. In this session we'll describe best practices for "configuration as code" in a Kubernetes environment. We will demonstrate how a properly constructed containerized app can be deployed to both Amazon and Azure using the Kublr platform, and how Kubernetes objects, such as persistent volumes, ingress rules, and services, can be used to abstract from the infrastructure.
