  • Clouds Grow, But Can IBM i Follow?

    August 29, 2016 Timothy Prickett Morgan

    Until cloud computing–meaning virtualized compute, storage, and networking that is sold under utility pricing–is absolutely the norm in the data center, we will be talking about what is and is not cloud and how fast it is or is not. The prognosis is that investments in public cloud computing are going to continue to grow fast, much faster than the overall IT sector, which has been coasting along more or less level for years.

    That placid surface on overall IT spending masks the churn underneath the surface, so don’t be fooled.

    According to researchers at IDC public cloud spending is expected to hit $96.5 billion in 2016, and moreover is expected to increase at a compound annual growth rate of 20.4 percent between 2015 and 2020, rising through $195 billion by the end of the forecast period. IDC breaks the cloud market into the same infrastructure, platform, and software layers as the rest of us do, but further refines the software part of this as applications as a service, system infrastructure as a service, and application deployment and development as a service (what we call platform clouds) separately. This cloudy software component of the public cloud stack accounted for 83.7 percent of revenues in 2015, with the remaining 16.3 percent being for foundational infrastructure services for raw compute, storage, and networking. This may come as a surprise to many, and so might be the fact that the IaaS and PaaS layers of the public cloud are forecast to grow faster than SaaS.

    “Cloud software will significantly outpace traditional software product delivery over the next five years, growing nearly three times faster than the software market as a whole and becoming the significant growth driver to all functional software markets,” explained Benjamin McGrath, senior research analyst for SaaS and business models at IDC. “By 2020, about half of all new business software purchases will be of service-enabled software, and cloud software will constitute more than a quarter of all software sold.”

    Spending on public cloud services seems to be mirroring IT spending in the overall global economy, and IDC says that the discrete manufacturing, banking, and professional services sectors are the big cloud spenders. The media, telecommunications, and retail sectors will see the fastest growth between 2015 and 2020, and 20 different sectors that IDC tracks will see cloud spending double over those five years, just as the market at large.

    This is just another way to say that cloud is becoming normal for a lot of workloads at companies. Just as companies have been willing to pay a premium for the AS/400 and its follow-ons because of the integration, security, ease of programming, and ease of administration of the platform, companies are willing to pay a premium for cloud services that allow companies to deploy fast and flexible infrastructure. One only need look the latest financial results for Amazon Web Services to see that.

    In the second quarter, AWS saw revenues increase by 58.2 percent to $2.89 billion and operating income rose by 135.9 percent to $718 million. The revenue growth rates are cooling for AWS a little bit, but the company is learning how to extract more profits from its investments in hardware, software, and system management expertise. This is the game, and it is no wonder that so many companies want to start IBM i clouds and offer similar services to RPG and COBOL shops that currently run atop on-premises equipment.

    When it comes to consuming web APIs on your IBM i, your options often boil down to one of two things:

    First, you end up having to rely on a variety of open source and non-RPG solutions. This adds developer complexity, taking away time that could have been better spent invested in other projects. Of course, open source software is free, but generally comes at the cost of no professional support, which adds an element of risk in your production environment. RXS is completely professionally supported, and is complemented by a staff of trained IBM i developers who can address your nuanced development challenges, head on.

    Second, if you choose not to pursue an open-source solution, you’re often left having to shake up your current program architecture with proprietary software, external dependencies, and partial RPG implementations – many of which are sub-par compared to RPG-XML Suite’s wide range of features. RXS aims to simplify the efforts of developers with tools like code generators, useful commands, and subprocedures written in 100% RPG – no Java. Because they are entirely RPG, the RXS subprocedures are easy to add to new or existing ILE programs and architecture, helping to cut your development time. RPG-XML Suite offers powerful capabilities in an accessible, easy-to-implement format.

    With RPG-XML Suite, you can accomplish a variety of complex tasks, such as:

    • Calling REST and SOAP web services from your IBM i
    • Offering APIs from your IBM i
    • Creating JSON & XML
    • Parsing JSON & XML
    • Text manipulation, Base64 encoding/decoding, CCSID handling, hashing and encryption functions, and more.

    To try RXS for yourself, we recommend a free proof of concept, which not only gives you access to all of RPG-XML Suite’s subprocedures and utilities but also includes a tailor-made software demonstration that can be used as a starting point for your future API implementations.
