Three Things To Consider About Virtual Storage Appliances

StorageNetworkingMany people seem to think that in this brave new world of converged infrastructure and software-defined everything, the era of standalone storage and networking is coming to an end. Indeed, it’s becoming quite popular to think differently about storage. There are new types of clustered and distributed storage options, like Ceph and Gluster, that rethink the way storage is delivered and built. There are virtual storage appliances (VSAs), like the HP StoreVirtual VSA and NexentaVSA, that essentially replicate standalone hardware in a virtual machine. There are also hybrid approaches, where companies like Nutanix, Scale Computing, and Simplivity deliver a clustered file system that’s tightly integrated, via virtual machine, with their products.

How to Prevent Agile Initiatives from Failing

agilecloudIn my previous post I highlighted a number of patterns that lead to failures of agile initiatives. The post generated a lot of conversation and a few comments, so instead of responding to everyone individually I will address all of the questions and comments in this post. Let’s look at each fail pattern and discuss strategies to prevent agile from failing. Continue reading How to Prevent Agile Initiatives from Failing

Big Data Security

CloudComputingAt the recent Misti Big Data Security conference many forms of securing big data were discussed from encrypting the entire big data pool to just encrypting the critical bits of data within the pool.  On several of the talks there was general discussion on securing Hadoop as well as access to the pool of data. These security measures include RBAC, encryption of data in motion between hadoop nodes as well as tokenization or encryption on ingest of data. What was missing was greater control of who can access specific data once that data was in the pool. How could role based access controls by datum be put into effect? Is such protection too expensive given the time critical nature of analytics or are there other ways to implement datum security? Continue reading Big Data Security

The New Management Platforms for the SDDC Management Stack and the Cloud

Legacy solutions from IBM, BMC, HP and CA are not going to be the foundations upon which the management stacks for virtualized data centers, the SDDC, private clouds, hybrid clouds and public clouds will be built. Rather a new ecosystem of management vendors is going to emerge with a new set of leaders providing the core platforms around which the SDDC and clouds are managed.

Identity in the Secure Hybrid Cloud

When it comes to the secure hybrid cloud, Identity has many different definitions from a device a user is using to the combination device, location, password, and other multi-factor authentication means. Even with all the technology there is still the question of where the identity store lives (the bits that contain the identity for all users, devices, etc.) as well as how do you prove identity once the user goes somewhere within the cloud which is outside your control?

Shopping for Solutions to Manage the SDDC and the Cloud

SDDC.Management.Stack.Reference.ArchitectureIn our series of posts about the reference architecture for the software defined data center and the cloud, we make the case that the requirements for managing a SDDC and the cloud are so different from the requirements for managing dedicated physical hardware that these requirements will be met by new vendors instead of legacy management vendors. Continue reading Shopping for Solutions to Manage the SDDC and the Cloud
