Cloud infrastructure providers like Amazon are putting out the technology that the enterprise and SaaS providers need to move beyond testing the waters and take advantage of the Cloud today. The latest, and most important from the data storage perspective, is Amazon’s Elastic Block Store, or EBS.
Over the years we’ve witnessed a shift to hosted IT infrastructure where all the issues surrounding the physical plant are consolidated and managed by a specialist service. In the past six months we've witnessed the incredible rate at which cloud computing has really taken off and is now allowing businesses to shed the problems of ordering, racking and maintaining servers and disk storage systems.
The public cloud is now knocking down the barriers to a broader business audience that has seen the advantages of “pay as you go” IT and not having to build or rent another data center. Why do that when you can instantly spin up 10, or 1,000 virtual server instances at a fraction of the cost? Cloud infrastructure providers, like Amazon, are putting out the technology that the enterprise and SaaS providers need to move beyond testing the waters and take advantage of the cloud today. The latest, and most important from the data storage perspective, is Amazon’s Elastic Block Store, or EBS.
Datasets, Throughput and Snapshots
In short, EBS is a SAN (Storage Area Network) in the cloud that works with Amazon’s existing Elastic Compute Cloud (EC2) and Simple Storage Service (S3). One hurdle for many businesses has been the data storage and throughput limits for each instance. Now you can allocate a disk volume of 1GB to 1TB from what is a virtually endless SAN in the cloud, and attach it to an instance running in EC2. The volume is stored on redundant disks and has a lifetime that's separate from any instance on which it is mounted. This is important, as previously the data was lost when an instance was no longer used. Now you can unmount it, and later remount it on another instance. We’ll look at how to get very large datasets using EBS into the cloud.
Another benefit of EBS is taking advantage of the snapshotting feature. You can snapshot a volume to S3, where it is stored with the redundancy and durability of all objects on S3. Moreover, successive snapshots are incremental providing a very powerful and efficient backup capability for volumes.The ability to take snapshots is a complex feature, but RightScale provides some cool scripts to make it even easier to freeze all data access while the snapshot is taken to ensure that the data on the snapshot is consistent.
The RightScale Dashboard supports all the features of EBS and offers a number of additional features such as configuring volumes to automatically be attached to servers when these launch and track the ancestry of a volume or snapshot. What does EBS enable? In short: traditional processing on large datasets and reliable storage for many servers. But let's look at these two areas one-by-one.
Amazon Web Services are designed for scale. EC2, S3, SQS, and SDB are ideally suited for building large systems that process huge data volumes. The catch has been that they are geared towards modern service oriented systems using a non-relational database like Amazon SDB, and thrive on large numbers of simple servers (EC2). Business users have more traditional applications, such as relational databases, that require large datasets stored in a file system with a POSIX interface. While an EC2 X-large instance comes with about 1.4TB of local disk space, it is difficult to use in a production system. Populating the disk with data at boot time can take hours and backups, replication and restoring the data in case of an instance failure are all sore points. For up to 100GB the timescales are workable, but beyond that it gets difficult.

Dr von Eicken will be giving a technical session at SYS-CON's "Cloud Computing Expo" (November 19-21, 2008) - a major adjunct to the 4th International Virtualization Conference & Expo being held at The Fairmont Hotel in San Jose, CA - in which he will distill the unique characteristics of clouds and describe how to best think about deployments in the clouds.
Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.

The Internet of Things is tied together with a thin strand that is known as time. Coincidentally, at the core of nearly all data analytics is a timestamp. When working with time series data there are a few core principles that everyone should consider, especially across datasets where time is the common boundary. In his session at Internet of @ThingsExpo, Jim Scott, Director of Enterprise Strategy & Architecture at MapR Technologies, discussed single-value, geo-spatial, and log time series data. By focusing on enterprise applications and the data center, he will use OpenTSDB as an example t...

The Domain Name Service (DNS) is one of the most important components in networking infrastructure, enabling users and services to access applications by translating URLs (names) into IP addresses (numbers). Because every icon and URL and all embedded content on a website requires a DNS lookup loading complex sites necessitates hundreds of DNS queries. In addition, as more internet-enabled ‘Things' get connected, people will rely on DNS to name and find their fridges, toasters and toilets. According to a recent IDG Research Services Survey this rate of traffic will only grow. What's driving t...

Enthusiasm for the Internet of Things has reached an all-time high. In 2013 alone, venture capitalists spent more than $1 billion dollars investing in the IoT space. With "smart" appliances and devices, IoT covers wearable smart devices, cloud services to hardware companies. Nest, a Google company, detects temperatures inside homes and automatically adjusts it by tracking its user's habit. These technologies are quickly developing and with it come challenges such as bridging infrastructure gaps, abiding by privacy concerns and making the concept a reality. These challenges can't be addressed w...

The definition of IoT is not new, in fact it’s been around for over a decade. What has changed is the public's awareness that the technology we use on a daily basis has caught up on the vision of an always on, always connected world. If you look into the details of what comprises the IoT, you’ll see that it includes everything from cloud computing, Big Data analytics, “Things,” Web communication, applications, network, storage, etc. It is essentially including everything connected online from hardware to software, or as we like to say, it’s an Internet of many different things. The difference ...

The major cloud platforms defy a simple, side-by-side analysis. Each of the major IaaS public-cloud platforms offers their own unique strengths and functionality. Options for on-site private cloud are diverse as well, and must be designed and deployed while taking existing legacy architecture and infrastructure into account. Then the reality is that most enterprises are embarking on a hybrid cloud strategy and programs. In this Power Panel at 15th Cloud Expo (http://www.CloudComputingExpo.com), moderated by Ashar Baig, Research Director, Cloud, at Gigaom Research, Nate Gordon, Director of T...

The security devil is always in the details of the attack: the ones you've endured, the ones you prepare yourself to fend off, and the ones that, you fear, will catch you completely unaware and defenseless. The Internet of Things (IoT) is nothing if not an endless proliferation of details. It's the vision of a world in which continuous Internet connectivity and addressability is embedded into a growing range of human artifacts, into the natural world, and even into our smartphones, appliances, and physical persons. In the IoT vision, every new "thing" - sensor, actuator, data source, data con...
