Yesterday’s trip to Cloud Camp Boston was most interesting. The keynote gave a good overview of what cloud computing is, where it came from and where it is headed. Continue reading “From the Cloud Camp”

Amazon EC2 system restore
Recently, one of our small EC2 instances failed. While we had Nagios monitoring it, Nagios only provides alerts when services fail, or when the host goes down. In this case, the failure was on Amazon’s side- the hardware where our instance resided was failing.

Cloud Computing and Virtualization for Big Data
Cloud Computing and Virtualization Services
TNR Global offers different cloud computing and virtualization solutions depending upon your needs. Whether you run your own data center, or want to run on hosted infrastructure services such as Amazon Elastic Compute Cloud (Amazon EC2) and Rackspace Hosting, we can assist in assessing costs and performing migrations to the cloud. We have the expertise to leverage the full spectrum of Amazon Web Services (AWS) and Rackspace to work for small and mid-sized businesses, laboratories and organizations. We have over 4 years of experience in cloud computing platforms. Our extensive knowledge of the AWS platform and tools allows you to avoid costly mistakes and false starts, getting you up and running quickly, securely and scaled just right.
Virtualization:
We can help you improve your IT infrastructure with a Virtualization Platform. Virtualization reduces expense, consolidates servers, reduces overall downtime, and improves efficiencies through automation. We use Open VZ, Virtuozzo, Xen and Eucalyptus virtaulization technologies to streamline your IT department.
Migration:
We create a cloud computing environment tailored to the requirements of your application or development needs. We specialize in methodologies and tools that help in migration, porting, testing, and emulating systems in the cloud.
Custom AMIs:
TNR Global can create your own Custom Amazon Machine Image that will wrap your operating system, domain specific tools and applications, and shared data in one easily deployable package.
IT Outsourcing:
At TNR Global we believe in freeing innovators to innovate. Our deployment and maintenance services allow businesses and laboratories of any size to utilize highly secure, enterprise quality, massively scalable IT infrastructure and experienced, dedicated and available staff.
Consulting Services:
- cost comparisons and risk assessment for application hosting: ‘in the cloud’ vs. traditional data centers
- security audits
- suggestions for integration and best use of new services from AWS including ingestion and structure of your data
- solutions specifications development
- solutions implementation

Since the fall of 2007, TNR Global has been working with Amazon Web Services and specifically Elastic Compute Cloud (EC2) services to help mid-sized companies leverage the benefits of the cloud computing platform. Cloud computing offers application vendors, publishers, and researchers increased agility/time to market, elasticity, minimal capital expenditure, and pay-as-you-go pricing.
TNR Global specializes in methodologies and tools that help in migration, porting, testing and emulating applications in the cloud.
We offer expertise on the full spectrum of services related to Amazon Web Services. Our experts will work with you to provide cost comparisons and risk assessment for application hosting ‘in the cloud’ versus traditional data centers for ongoing deployment, shorter-term prototyping or even one-time computations. If it is determined that AWS is the best alternative, we provide efficient, secure, cost-effective and properly scaled configuration, creation, and deployment of application platforms using the full range of AWS offerings. Our expertise in building custom images on EC2 allows us to offer unique solutions tailored for each customer.

Amazon EC2 ’steals’ from you
As we implement more systems in the EC2 architecture, we are noticing a not so insignificant amount cpu cycles ’stolen’. What is a ’steal’ time? It is CPU time that is taken by the Xen hypervisor for something else other than your processes- from what I have read, other people’s processes. What we need to understand is how this affects performance. Does it truly matter? We have one virtual system that consistently has steal time of between 6-12%. That would mean that 6-12% of the CPU time we pay for is being used for instances other than our own. We will have to research this more to see what the true impact is on our systems, and if there is a way to mitigate it.
