[5 Jul 2012 | Comments Off on Developing Cloud Software with IBM Rational Tools | ]

To achieve the promises of cloud computing, a developer has to think in a broader fashion. A number of actors collaborate together in cloud use cases:
* The cloud service developer develops software and other assets for consumption on the cloud.
* The cloud service consumer requests cloud resources and approves business expenditure. Cloud service consumers might include users, administrators, and business managers.
* The cloud provider providers a cloud service to consumers.
The scope of this article is intentionally broad to cover these aspects of application development and operation giving examples of how …

Continuous integration is a software development practice in which members of a team integrate their work frequently; usually each person integrates at least daily which leads to multiple integrations per day. Each integration is verified by an automated build (including test) to detect integration errors as quickly as possible. Continuous integration, especially in the early stage of development process, can greatly improve the efficiency and help find potential issues as soon as possible.

IBM® PureFlex System is a cloud-ready, expert, integrated system that brings together the infrastructure and application layer with proven patterns and can be specifically optimized to meet specific needs, providing all of the infrastructure elements required to run your workloads in a single system. To further the IBM PureFlex System advantage with a speedy time-to-deployment, there is the IBM Virtual Appliance Factory toolkit that automates the deployment of your cloud appliance — your application along with the appropriately configured operating system and middleware — onto Kernel-based Virtual Machine (KVM) and …

[30 Apr 2012 | Comments Off on Configuring a Complex Cloud Test System | ]

As Cloud applications continue to get more complex, it is more and more difficult to deliver them. This article demonstrates how to establish a working, easily repeatable Collaborative Lifecycle Management system that runs on WebSphere Application Server using DB2 as the database. IBM Workload Deployer and the Rational Team Concert CLM feature are used. The end result is a topology that testers can reproduce in a daily, on-the-fly build to verify app defects and builds, perform smoke tests, and enable other testing activities. This complex cloud configuration allows functional verification …

[19 Apr 2012 | Comments Off on Elastic provisioning on IBM SmartCloud Enterprise using ITM | ]

This video demonstrates the capability to automatically provision new servers on the IBM SmartCloud Enterprise based on event detected by IBM Tivoli Monitoring. This is the basic concept of elastic provisioning.

[27 Mar 2012 | Comments Off on Best Practices and Tools for IBM SmartCloud Enterprise | ]

This article describes the use of software bundles, image management, and other tools on IBM SmartCloud Enterprise to solve practical problems in enterprise IT management. A software bundle is a collection of software installation files, configuration files, and metadata that can be deployed on a virtual machine instance. This article presents an overview of software bundle and image management concepts available on the IBM SmartCloud platform. It explains the resource model, compares this platform to other software package management platforms, discusses use cases and surveys the tools available. The concepts …

[21 Feb 2012 | Comments Off on Repairing Cloud Virtual Machine Cloning Errors | ]

One of the benefits of exploiting virtual system images is the capability to clone them so they can be reused in different environments. External data provisioning requirements such as network configurations like IP addresses can cause problems when cloning a virtual machine to use in a new environment. If the external data is not available during the process, the reconfiguration of the VM will likely incomplete.

[14 Feb 2012 | Comments Off on Virtual Machine Security in the Cloud | ]

Security is a key factor of deployment of computing resources within an enterprise and even more important when moving those resources in the Cloud beyond the physical walls of an enterprise. With the growth of cloud-based infrastructures, sometimes inexperienced or unaware users do not consider how important security is in a public cloud. This article discusses some of the topics which need to be considered about security when a virtual machine (VM) is provisioned in IBM® SmartCloud Enterprise.

[6 Feb 2012 | Comments Off on Measure UI Performance on IBM SmartCloud | ]

Tuning web application user interface performance poses two challenges: How do you target and obtain detailed performance metrics for special requests automatically and how do you calculate accurate page performance metrics from a user experience? This article answers those challenges by debuting a framework for IBM SmartCloud Enterprise that lets you establish an automated, UI performance-measuring system that engages Fiddler, a web debugging proxy. This article explains the framework, Fiddler, the performance metrics that are captured by the system and how they are important to UI performance measurement.

[30 Jan 2012 | Comments Off on Multi-tenancy Database in the Cloud | ]

In a multi-tenant environment, a SaaS company can reduce costs if it shares or reuses more of its resources. However, the more the company shares resources, the more risks it faces because an outage of a shared resource can potentially affect many customers.  This article discusses the considerations multi-tenancy database in the Cloud from a DB2 perspective.
