Breakfast with ECS: Most Wanted Cloud Storage Feature Series – Part 5: Superior Economics

Welcome to another edition of Breakfast with ECS, a series where we take a look at issues related to cloud storage and ECS (Elastic Cloud Storage), EMC’s cloud-scale object storage platform.

Hello folks!

Breakfast wtih ECSGlad to have you back on this ECS feature series journey.

In the previous blog of this series, we discussed ECS’ enterprise-class features. In this blog, we’ll discuss why ECS has superior economics.

Entering the public cloud is simple. But as the data you store in the public cloud reaches a certain scale, it becomes simply expensive. You have to pay for every single time you touch your data – you must pay someone else a small fee to store your data, and another fee each time to index it, like it, share it, download it or even to just plain look at it.

ECS for OpenStack is a ‘swifter’ route to enterprise-grade persistent storage

A vast majority of our enterprise customers continue to ask us about using EMC Elastic Cloud Storage (ECS) with their OpenStack infrastructure – and how easy it would be to use ECS as a drop-in replacement for OpenStack’s object storage, Swift. The good news is that, with the release of ECS 2.2.1, ECS integration for OpenStack just got easier – as I’ll explain.

OpenStack Swift is great to get started with OpenStack. However, as you move out of proof-of-concept (POC) into larger production environments, the platform weaknesses swiftly show up – keeping costs under control while maintaining compliance- typical enterprise grade features in a persistent storage system at scale is very difficult.

OpenStack Swift has gaps to address to be truly enterprise-ready

OpenStack Swift falls short of being a true enterprise-grade production-ready solution. It is not simple to scale out to thousands of nodes, has limited erasure coding support, and performance for both large and small data objects is not on par with commercial object storage offerings.

Further, as you grow across sites you will require ‘strong’ data consistency – to ensure that changes to a dataset in one location are immediately reflected in the copies of the dataset in other locations. OpenStack Swift provides only ‘eventual’ data consistency – which can leave your applications struggling to handle synchronization across multiple sites.

OpenStack Swift purely focuses on accessing objects via the Swift protocol leaving out other protocols in use by applications today. For example, if you want to analyze your data using Hadoop, you will first need to move your data from OpenStack into a separate HDFS cluster – which will cost your time, resources and datacenter space. Similarly NFS access to OpenStack Swift can only be achieved via external NFS Gateways.

An enterprise-grade object storage for OpenStack

ECS is a cloud-scale object storage platform. It is an attractive drop-in replacement for OpenStack Swift – with its ability to handle massive scale, production-grade performance for objects (large or small), built-in metadata search capabilities, multi-protocol access on the same data (object via Swift API or S3, NFS and HDFS for in-place Hadoop analytics), multi-tenancy, and active-active geo-distribution with strong consistency.

With the release of ECS 2.2.1, featuring ‘ECS Swift’, you can now easily provision and use ECS object storage from OpenStack.

Seamlessly integrate ECS into your OpenStack environment

In OpenStack deployments, identity and access management is handled by OpenStack Keystone. To enable integration with OpenStack, ECS 2.2.1 offers native support for interop with Keystone v3.0.

Out of the box, ECS can now register itself with Keystone, and use Keystone to authorize ECS Swift service requests. This integration also enables Keystone to be the ‘single source of truth’ with respect to user identities, eliminating the need for duplication of identities in ECS.

The behind-the-scenes interaction between ECS and OpenStack Keystone works as follows: if you are an OpenStack user, when you authenticate to Keystone, it will present digital credentials explaining who you are. Keystone verifies your identity and presents you with a Keystone token. You then make a request to the ECS Swift service with this token. To serve the request, ECS forwards the token to Keystone for token authorization, and ensures that you are authorized to perform the requested action, prior to rendering the request.

 

ECS Intergration with OpenStack

Keystone integration allows ECS to be a drop in replacement for OpenStack Swift. But our plans don’t stop here! With upcoming releases we will continue to enhance ECS for tighter integration with OpenStack (support for Manila File Services and support for OpenStack metadata search) – so keep watching this space.

Breakfast with ECS: Most Wanted Cloud Storage Feature Series – Part 4: Enterprise Class

Welcome to another edition of Breakfast with ECS, a series where we take a look at issues related to cloud storage and ECS (Elastic Cloud Storage), EMC’s cloud-scale object storage platform.

Hello folks!

Welcome back to ECS feature series!Breakfast with ECS Enterprise

In the previous blog of this series, we discussed ECS’ smart capabilities. In this blog, we’ll discuss how ECS is built to serve the needs of enterprises.

When selecting a cloud storage vendor, enterprises have many questions: Is this cloud built for scale? Is it secure? Is it able to handle the different business applications needed for long term business growth? Will it simplify my operational management? We at EMC were thinking these exact things when we introduced ECS.  How can ECS improve your data privacy, manageability and operation efficiency?

Watch the video below and find out the answers.

ECS is enterprise-grade yet has incredibly low storage overhead, and is capable of storing nearly 4 PB of data in a single rack. Stay tuned for the next blog discussing more about ECS’ economical capabilities. Yes! You don’t want to miss it.

BreakfastWelcome to another edition of Breakfast with ECS, a series where we take a look at issues related to cloud storage and ECS (Elastic Cloud Storage), EMC’s cloud-scale object storage platform.

Hello folks!

Glad to have you back to this educational journey of Elastic Cloud Storage (ECS) features.

In the previous blog of this series, you learned the market trend and why Elastic Cloud Storage (ECS) is one storage solution that can cater to all of your needs. From this blog, you’ll learn more about the specific features that make ECS so awesome.

As traditional systems capture and store data based on data type, they have to manage different silos of data. While they give you consistency and speed, trying to manage these pools of data is like facilitating a conversation where no one speaks the same language. It’s a path to some serious complexity.

So, here we are! ECS is the one single shared storage that supports billions of files of all types and talks multiple “languages”, such as Amazon S3, OpenStack Swift, HDFS and NFS.

Check out today’s video below to learn more about ECS’ multi-purpose capabilities.

ECS is not only designed for multi-purpose, it is also “smart”. Check back for the upcoming blog introducing ECS’ smart features.
