Why BI in the Cloud?

Business Intelligence (BI) has been around for a while but recently, the interest in analytics and tools to support it have become increasingly popular. Previously, only large enterprises were able to afford the infrastructure and license cost to implement traditional business intelligence. However, the advent of the cloud is an opportunity for everyone to take advantage of the transformative power of data.

Traditional BI was typically a client server setup with companies typically shelling out for dedicated equipment in their own data center or a co-lo, requiring license fees for the software and a dedicated staff to manage all the equipment and to maintain the server. The more data that you had to analyze, the more equipment that you had to buy and the more staff that you had to hire. The massive amount of investment in this area became a sunk cost and some enterprises are still tied to this model despite the fact that new models have arisen to tackle the data challenge.

The Cloud

The cloud opens up all new options for companies looking to either build out their own solution or to leverage new products that are native to cloud. There are currently three generally accepted cloud delivery models: Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). I consider SaaS and IaaS to be the models that will be the most effective for BI.

One of the concerns that are often raised regarding the cloud is security – this in particular with BI since it involves data and sometimes personal information. The question then is, how will a provider that specializes in managing a data center (in the case of IaaS) or large-scale application and data hosting (in the case of SaaS) any less secure than a company who’s focus is on their own business and not on securing the data center? You will need to verify a few things depending the delivery model that you are using. For SaaS, you will want to ensure that the provider can give you secure login and authentication, the ability to define granular levels of access, SSL, and the option of encryption at rest. For IaaS, the customer is typically responsible for setting up security but you will want to see ISAE 16, ISO 7001 certification, DDOS mitigation as well as options to provision firewalls and load balancers. The Cloud Security Alliance (CSA) is currently working on their Security, Trust and Assurance Registry (STAR) which will make it easier to determine security criteria for a cloud provider but it is currently only in the preview stage.

Deciding which Cloud Model

If you are interested in just providing data and then having software available to analyze, manipulate and create reports, SaaS products may work for you. Example of some SaaS BI companies are BIRST, PivotLink, and GoodData. All of them provide the BI-stack, which is a method for extracting, transforming and loading data, a place to store the data, and a front-end to create ah-hoc reports and dashboards. The advantages of using this style of BI is that all the management of the infrastructure and software is handled by the vendor. There is also minimal up-front costs – the model is to simply pay for what you use.

If you want to build your own BI platform, you can leverage IaaS and open-source software. You will need to find an IaaS vendor that best suites your needs – Amazon Web Services, GoGrid and Rackspace are the leaders in this space. Using IaaS, you will have full control of your infrastructure – you can determine how many servers to spin up, the security you want to use and how you want to store the data. You will also need to build out the software assuming that you have that expertise in-house. Some good open-source options are Talend for data migration and manipulation, Pentaho for data integration and analytics, BIRT for reporting and MySQL or Postgres for the database. This model requires more system administration expertise and developer resources to build out a custom BI solution but this may be worth the investment if you want tighter control of your product or have very specific custom needs. In either case, if you can leverage the features offered in open-source software, your will also minimize up-front costs and will pay for the infrastructure that you use – with the option of spinning up servers to meet demand or remove servers when they are no longer needed. You can start off with small 1GB server and expand to more cores, more RAM and more storage quickly and easily.

In addition, the flexibility of the cloud gives you the option to expand your infrastructure if you need to incorporate a Big Data solution to meet a particular use case. Currently, most of the popular technology is open-source such as Hadoop, MongoDB and Cassandra. I discuss Big Data in more depth in a previous blog post.

Ultimately, you may decide that you need all the features that are offered by a traditional BI vendor or have already made the investment in a particular infrastructure or technology. After all, these companies have been around a long time and there are many talent individuals who are well-versed in these products. However, if you are interested in lowering costs and off-load the infrastructure and software work to another vendor or are new to BI and want to get started with minimal up-front costs, the cloud based BI solutions might be the right option for you. Instead of having to project growth in order to order the hardware up-front, you will have the ability to pay-as-you-go, and add infrastructure and cost only as your growth demands. DASHbay is experienced in both delivery models discussed here and we can provide the right analytics expertise and development experience for your BI needs. Considering the growth in data, the flexibility of the cloud and the much needed analytic features of a BI solution work well together to provide a powerful, low-cost and scalable solution. Make sure that you work with the right vendors and partners to make your project a success!

Customer retention metrics

Last night (Tue July 19th), I was fortunate to be able to speak to the SVForum Business Intelligence special interest group (SIG).

After introducing the audience to DASHbay, I took them through an implementation we did using our Quick Analysis practice, which leverages open source software (especially BIRT and postgresql), cloud computing (on AWS), and rapid, iterative development.

The implementation itself was a dashboard, built with BIRT in less than a week and showing metrics for account acquisition and retention. The metrics help any business track not just how well they are acquiring customers, but how well they are keeping them.

Our customer was able to get at the metrics via a URL to a server running in the cloud, set up just for them. It’s a great way to leverage cloud computing: no IT procurement costs or delays, and you only pay for it while you need it.

We talked about DASHbay’s Report Server product, which among other features, allows us to capture any useful piece of the report, and include it in any web page. It also provides permissioning and authentication, taxonomy for organizing reports, and more.

I got an excellent reception from the audience, and was pleased with the reaction and discussions afterwards. Thanks to all who attended!

If you didn’t get a chance to be there, please get in touch so we can talk to you more about our Report Server for BIRT, our Quick Analysis Service, or many custom BI and Data Analytics services. Customer Retention is one very useful application which we can provide, but our tools and techniques are applicable to most common business analysis problems.
