One of the most appealing benefits of cloud deployment is the ease of use and the flexibility of adding or removing compute capacity. You can dynamically allocate resources based on the changing workloads, which give you the flexibility in managing your compute cost.
AWS Auto Scaling enables you to closely follow the demand curve for your applications, reducing the need to provision Amazon EC2 capacity in advance. For example, if your CPU Utilization goes over 70% you can add additional EC2 instances. Similarly, if your CPU Utilization goes down above a threshold, you can remove EC2 instances.
Similarly, Rackspace auto scaling can be Schedule-based and Event-based. You can prepare for a burst of traffic during specific holidays or during peak hours by creating a schedule or you can monitor specific events like a CPU load and provision additional capacity.
Microsoft Azure provides manual, automatic or scheduled based scaling of your application, where you can add additional CPU, or increase the queue messages on the target machine.
In the Cloud Foundry based PAAS platform, auto-scaling an application to hundreds of instances using BOSH auto-scaler is as simple as defining auto scaling rules and this can create multiple instances of your applications.
$ cf scale myApp -i 500
While auto scaling flexibility is beneficial and a required feature for any cloud deployment, this can quickly add cost to your cloud deployment. More compute resources means more cost and this can spiral quickly without addressing the real problem - is your app using the resources you've already provisioned properly? Do you even have that level of visibility? Are you closing the visibility gap?
Ever increasing visibility gap
What is actually needed is complete application visibility to address your performance issues. The first step is to optimize your apps and benchmark the performance and get the visibility you need. The next step is Auto Scaling, which can enhance your application performance to meet the unknowns.
How do you prepare your application to meet this challenge?
To answer this question, we ran some tests and analyzed the results. To start, we deployed a standard e-Commerce store application on a LAMP stack from couple of cloud providers. The e-commerce store sells electronics and has the full functionality of an e-Commerce site. The key transactions on this store are:
- Register as user
- Place order
- Receive email
- Check status of order
- Payment type (check or money order)
e-Commerce Store Application in the Cloud
This app is pre-packaged from Bitnami and runs on an open source LAMP stack that allows visualization of infrastructure.
The infrastructure consisted of web/app servers and a MySQL database in multiple cloud sites on the US East and West Coasts and in Europe.
Deployment of e-Commerce App on Multiple Clouds
We have Multi-Tenants Firewalls and Load Balancers. The e-Commerce platform is RHEL 64 bit OS, Apache, MySQL, PHP and Magento. The Webserver / Application Servers are in DMZ (1vCPU x 4 GB x 10 GB Disk) and the MySQL DB Server in Internal (1vCPU x 4 GB x 10 GB Disk)
Next, we used Compuware Synthetic Monitoring 2.0 to script key transactions on the store. We generated a steady synthetic load mimicking real users from various backbone and last mile locations and across ISPs. We scripted single URL and multiple step tests to measure the availability and performance of the Web site in the cloud.
Synthetic Tests Scripts
We then instrumented the back end with the Compuware dynaTrace solution by deploying the PHP/Web agents across all the tiers of the application.

We are reaching the end of the beginning with WebRTC, and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) i...

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...
