Guidelines For Enterprises Choosing To Migrate On The Cloud

Choosing To Migrate On The Cloud 

Categorizing the Cloud Computing Providers

Cloud providers offer a variety of services to all categories of cloud users including individuals, small businesses, and enterprises. For enterprises, the choice of type of service to subscribe is a bit intriguing task as their requirements of IT vary. Some enterprises need secure data storage while others need infrastructure-as-a-service or platform-as-a-service. The enterprise’s IT architecture is pivotal in defining the cloud service requirement. David Linthicum, an industry expert and thought leader, has categorized the services that an enterprise needs from cloud providers in his book “Cloud Computing and SOA Convergence in Your Enterprise”, excerpts of which were published by InfoWorld Media Group Inc. These categories are: storage, database, information, process, application, platform, integration, security, management, testing, and infrastructure.

How cloud providers offer these services is further categorized into two types:

Fine-grained Solutions Providers

These providers offer specific solutions to the enterprise needs and problems and do not offer complete platforms. Their services include storage, database, information, process, integration, security, management, and testing.

Coarse-grained Services Providers

These providers offer complete platform. The coarse-grained services include application, platform, and infrastructure. Of course, these so called coarse-grained services are made up of a number of fine-grained resources, for example, a platform-as-a-service provider may offer storage, process, security and testing service as a package. Though course-grained providers can meet all cloud computing needs of an enterprise and is easier to choose, the issue of optimization of resource usage becomes eminent due to different architectural requirements of different enterprises. Thus, a number of fine-grained services and solutions can better fit your IT architecture as you can choose various components of cloud computing solution to effectively meet your specific requirements. Cloud computing providers can also be categorized by enterprises based on architectural components:

1. Processes

The service components include application, platform, infrastructure, process, and integration. An example of this category is process service by Appian Anywhere.

2. Data

The service components include application, platform, infrastructure, storage, database, and information. For example, infrastructure service via Amazon Elastic Computing Cloud (EC2) and database service via Amazon Simple DB

3. Services

The service components include application, platform, infrastructure, and information. An example of this category is infrastructure service via Amazon EC2 To build a complete solution tailored to your need you can use different components from different providers. “You might store your data in Amazon Simple DB, as well as on the Amazon EC2 platform. Then, you might build and/or host the services on the Amazon EC2 platform, say, using an application server it provides on-demand within that platform”, writes Linthicum, “Finally, you could use Appian Anywhere as the platform where those processes live. Keep in mind that the processes are connected to the services, and the services are connected to the data. You’re just selecting the target platforms here.” The simplest arrangement using a single public cloud provider such as Amazon is process services for processes, infrastructure service for data, and infrastructure service for services, all via Amazon EC2.

David’s book also gives an example of a more complex service involving a number of providers as process service via Appian Anywhere and application service via for processes, infrastructure service via 3Tera Cloudware and Amazon EC2, and database service via Amazon Simple DB for data, and infrastructure service via Amazon EC2 and 3Tera Cloudware, application service via platform service via of for services.

The deployment of other components like testing, security, management, and governance may follow. They can be deployed on-site or on cloud as per need of the enterprise.

This categorization generally helps enterprises be in a better position to decide which cloud providers are the best candidates to meet the requirements of enterprise’s IT architecture.

Yammer’s Integration With SharePoint – Part 2

Yammer’s Integration With SharePoint – Part 2

Read Part 1

Future Road Map of SharePoint-Yammer Integration

According to Jared Spataro, Senior Director, Microsoft Office Division, who also leads the SharePoint business and works closely with Adam Pisoni and David Sacks on Yammer integration, their next step would be integration with Office365. Summer of this year will witness an update in Office 365 service and customers will be able to replace the SharePoint newsfeed with Yammer. This feature is desired as many customers are worried about confusing their users with two different feeds, and this update will allow them to simply replace the “Newsfeed” link on the Office 365 global navigation bar with a link to According to Spataro, “We’ll also ship a Yammer app in the SharePoint Store so that end users can easily embed a Yammer group feed into a SharePoint site, creating a connection between groups and sites that will deliver the best of both worlds. The SharePoint newsfeed will continue to be the default social experience in Office 365, but the option to replace it with Yammer will be a valuable first step in the overall integration process.

The next step on the roadmap is known as “Deeper Integration” planned in fall this year, which will bring another update to Office 365 and deepen the integration. It will allow Single Sign-on (SSO) and seamless navigation. It means when user will click on Yammer link in the Office365 global navigation bar, Yammer will appear immediately below with links to get back to Office 365 services like Sites and Outlook. This converged look will also have new rich document capabilities and will integrate Office Web Apps to add editing and co-editing of Word, PowerPoint, and Excel documents. The bigger vision is making Yammer an underlying enterprise social layer across Office, Exchange, Lync, and Dynamics integrated into SharePoint, which seems a long term and complex endeavor.

The next year will witness continued updating of Office 365 with new social enhancements that would appear every three months. Incremental enhancements will combine social, collaboration, email, messaging, video, voice and line of business applications.

Industry Impact Analysis of Yammer SharePoint Integration

Gartner analyst Larry Cannell believes that this integration could be market-changing but what matters is how much time it takes. He said that companies shouldn’t start planning ahead of the time just based on Microsoft promises, and should not scrap their current enterprise social networking plans or implementation if they are fulfilling their requirement.

The long-term vision described at the SharePoint Conference was aspirational in nature. Microsoft’s post references this when talking about ‘Connected Experiences and says they will combine social, collaboration, email, instant messaging, voice, video, and line of business applications in innovative new ways.’ However, this is mostly a summary of what Microsoft already has said and enterprises should not get swept up in these grand visions and lose focus on what is really being delivered”, he writes in his blog. “Replacing SharePoint’s newsfeed is not as simple as embedding a Yammer feed”.

Companies need to evaluate their need of enterprise social collaboration and should not over-rely on promises before something concrete is visible from this integration.

Business Collaboration: Yammer’s Integration With SharePoint – Part 1

Yammer’s Integration with SharePoint 

Engaging Social Experience to Enhance Productivity of Business Collaboration


Microsoft’s acquisition of Yammer in mid 2012 for $1.2 billion has been continuously drawing IT managers’ attention as they looked upon SharePoint-Yammer integration as eye candy in business collaboration platform. Recently, Microsoft updated their roadmap issued in November last year and announced a detailed roadmap at Convergence 2013 for enterprise social collaboration through Yammer’s integration into SharePoint.

How Yammer Enhances SharePoint Experience

Before we discuss the updated roadmap, let’s have a look at Yammers social media platform capabilities that can enhance user experience in Microsoft SharePoint, one of the popular business collaboration platforms.

Yammer is the first and most powerful enterprise social network. It’s integration with SharePoint, the enterprise business collaboration platform, turns business collaboration into a mobile, social, and engaging experience. Yammer adds a real-time social layer to business collaboration core capabilities of SharePoint, which is regarded as a vehicle for more productivity by virtue of its capabilities for team and company-wide collaboration around files and projects, and conversations. Yammer mobile applications keep the users connected to conversations inside SharePoint while they are on the go.

How it works and Future Promises

Yammer feed that includes “My Feed” and “Group Feeds” can be embedded virtually into SharePoint sites to facilitate conversations within teams and among teams within a company. It also allows sending and tracking private messages to coworkers using a separate private messages tab, while new messages are managed through @mentions, replies, etc.

Since the integration supports single sign-on, SharePoint authentication credentials are sufficient to simultaneously log into Yammer through a single entry point. SharePoint’s built-in Web Part controls and templates are used to manage the Primary Yammer Web Part. Users without Yammer account can also view conversations if Yammer administrator configures read-only Yammer feeds. Unread Yammer messages are directly tracked in SharePoint. The recent addition is “Yammer Web Part for Office365” that enables embedding Yammer feeds using a web part specifically built for Office365 pages. The users can send links to documents, announcements and tasks from SharePoint to Yammer feeds for real-time collaboration. Searching is more informative and easy as relevant Yammer messages are displayed beside SharePoint search results. Activity Streams allow sharing of activity happening in SharePoint with your colleagues on Yammer.

Enabling Optimization of Cloud Usage – CloudCheckr

With the growing popularity of cloud computing, and enterprises opting for migrating significant chunks of their IT infrastructures and services on public clouds like AWS, the need for performance optimization is being realized as one of the major issues.

According to a report published by Ernst & Young, cloud computing has brought fundamental shift in IT altering the technology industry power structure, improved business agility for all industries and increased everyone’s access to computing, storage and communications power. However, the report also terms a multitude of factors that cloud service providers (CSPs) and cloud users (enterprises that subscribe to cloud services) must carefully consider. One of those factors is pricing and business model complexities arising out of highs and lows in IT assets utilization, which occurs due to the dynamic nature of business needs.

Map (CloudTweaks)

The metered model puts additional requirements on both providers and users to monitor and scale the usage of resources so that users are able to realize the promised cost saving through pricing based on ‘as-needed’ usage of IT infrastructure and applications.

The issue of vertical scalability is very important when considering the use of cloud computing because you are often charged based on computing resources used, much like the old mainframe model”, Lori MacVittie, subject matter specialist on cloud, writes in her blog. “If an application does not vertically scale well, it’s going to increase the costs to run in the cloud.

Cloud users, mostly small businesses and enterprises usually have limited expertise in managing cloud services, and require third party tools and advisors in order to utilize the public clouds efficiently and effectively. AWS has recognized this reality, and made its proprietary Trusted Advisor service free for the month March. A growing number of third party tools have also entered into the space to address this problem. CloudCheckr is one of the leading third party tools that claim to provide far more functionalities than Trusted Advisor.

CloudCheckr’s stated goal is to help public cloud users to improve performance and reduce costs simultaneously. CloudCheckr is a recently launched startup that offers its services free of cost until April 10. The startup has been successful in adding 400 new users in past 60 days despite limited marketing efforts.

The startup claims to help enterprises in following areas related to cloud usage:

  • Resource tracking by using historical data, trend analysis, and change monitoring to enable cloud users understand their present position and future roadmap.
  • Increasing availability by identifying user exceptions and providing detailed instructions regarding how to remedy the issues.
  • Cost savings through right-sizing of resources and reducing spending without any impact on performance.
  • Optimizing subscription purchases by using different cost scenarios and recommending the best options.

CloudCheckr claims that they are far better than their competitors and Trusted Advisor.

Cloud Computing – What Is Ahead!

Cloud Computing – What is Ahead!

Top cloud computing trends of the current year

Experts have started to believe that 2013 is going to be the year when enterprises are likely to cease worrying about cloud related security issues, and the market will see increasing popularity of cloud services. These speculations are based on industry surveys conducted by many reputable market analysts and technology reviews.  It is predicted that year 2013 will witness growing popularity of hosted services and solutions, and more companies to migrate their prime IT assets to the cloud as they see more returns from cloud technologies.

The leading cloud computing trends for the current year are summarized below:

  • Cloud will remain popular platform for collaboration

Surveys suggest that enterprises will continue to use cloud for collaborative tasks such as application development, online communication, and software testing. Google and Amazon to remain leading collaboration service providers among public clouds.

  • Enterprises will see cloud as a solution to their disaster recovery needs

Enterprises will find cloud infrastructures as a most viable solution for their data storage, archiving, and disaster recovery needs. With enhanced security features, cloud providers will start emerging as trusted partners.

  • Cloud to keep enhancing cost savings and flexibility

Cloud computing will continue to remain popular for offering more cost saving options and enhanced flexibility of deployment and expansion. Enterprises are of the opinion that they have met their targets of cost cutting by adopting cloud services and will continue using cloud services for enhanced business value.

  • Public cloud offerings to remain popular

It is expected that public cloud offerings will continue to remain popular among developers than internal cloud infrastructure due to its speed and agility. Internal cloud offerings will face more requirements from developers that have already gotten use to the flexibility and speed offered by public cloud offerings.

  • Price competition between large cloud providers

Enterprises will see increased price competition between largest storage providers like Google and Amazon. It is expected that even the companies that stand firm on pricing will also consider offering value added services to beat the competitors.

  • General purpose cloud offerings to stay popular

Compared to industry specific cloud solutions, general purpose cloud offerings will remain popular among enterprises as indicated by majority responses in a survey conducted by Everest Group and Cloud Connect.

  • VMware as top cloud platform

This year marks VMware as preferred cloud platform as compared to other leading cloud platforms, including OpenStack, popularized by Rackspace, IBM SmartCloud and CloudStack, founded by Citrix Systems.

VMware also remains as top cloud virtualization vendor for the year. The others that follow are Microsoft Hyper-V and KVM.

  • Software-as-service (SaaS) to remain dominant trend in cloud development

Though companies are developing Infrastructure-as-service (IaaS) models for their private clouds, SaaS to remain still a dominant trend in cloud business model. The majority responded preferring SaaS model in a survey published by

According to Henrik Rosendahl, senior vice president of cloud solutions at Quantum, public cloud will be looked upon by IT managers as one of the best backup options as an extension of their virtual infrastructures. He is of the opinion that enterprises have long remained reluctant to use public cloud for backup and looked upon private cloud solutions in conjunction with VMware environments; however, emerging solutions making public cloud safer than before pose a challenge to existing thought.

Since the current cloud model is based on payment of subscription fees in accordance with the usage of resources by the enterprises, the subscription model will remain most popular business model for the cloud services.

Rosendahl predicts a new service and terms it as cloud-based disaster-recovery-as-service. “This area is gaining traction as enterprises and SMBs look for cost-effective ways to implement a DR strategy,” he says. Companies find it more attractive, and viable solution to use public cloud for backup and disaster recovery.

Popularity of cloud computing is also putting more demand on platform developers as enterprises have started realizing the need of a management framework that can work with all cloud environments used in the enterprises. Monitoring, identity management, and billing are the tasks that enterprise managers expect from the management framework without having to worry about which cloud environments to use. Platform developers have to face challenges of integrating different cloud environments and develop an application that can transparently monitor and report.

Resource allocation and exact accounting of utilization of resources by client enterprises are going to be the biggest concern of cloud service providers as they need to bill exactly what they are providing in the wake of fierce competition.

Like other technology fields, cloud technologies are also moving towards more innovation in terms of services and management; challenges are expected due to a massive increase in scale, complexity, and disruption in business models brought about by innovation.

It is expected that cloud platform vendors and cloud service providers will go with hand in hand to meet the challenges as well as harvest the opportunities that year 2013 is going to bring for them.
