<h3>Transform the IBM i-series/AS400 with DevOps: It's possible</h3>
<p>i-series is an IBM midrange computer system used extensively by many large insurance firms, retail businesses and banks. Being a legacy platform, projects executed on it generally follow the conventional waterfall development and slow releases.</p>
<p>Today's environment demands agility. Can you transform your i-series and be agile - YES. Have we done it - YES. Let me help you understand with an example.</p>
<p><strong>Here was the problem!</strong> </p>
<p>A leading global bank was embarking on a transformation program and wanted to reduce system downtime during scheduled outages of their Core application by routing the requests to a 'stand-by' application to provide business critical services.</p>
<p>The challenge was that the core platform was a 25-year-old monolithic application built on i-series and the entire concept to reality had to be achieved under very stringent timelines. Our team was up for it and we addressed the problem by successful implementation of DevOps & adopting agile principles. This is the first time it has been attempted by any service provider.</p>
<p><b>How did we address the problem?</b> </p>
<p>Infosys partnered with the client's tooling team and spearheaded the DevOps pipeline implementation. The deliveries happened in a MVP manner and shippable components were ready after every 2 sprints.</p>
<p><strong>Tools adopted:</strong> </p>

<p><strong>How did the client realize value from the solution?</strong> </p>
<p><strong>And our teams in turn benefitted from:</strong> </p>
<p>This journey however was not easy and we were faced with multiple <b>challenges</b>. DevOps tools for i-series were unexplored and we didn't have any SMEs available. Additionally, the application built across geographies added to the complexity making cleaning up of the non-standard source code types a tedious and prolonged activity. The biggest challenge was to change the team's mindset to move out of the conventional way of doing things and step into the new world. <br /></p>
<p>What made this even more difficult was that for stand-by application to perform its required task when the main application is down, it had to be installed on a separate <b>iASP</b> (Independent Auxiliary Storage Pool) from the main application.</p>
<p>Based on ARCAD consulting, it was suggested to install one ARCAD instance per iASP which would come with a heavy licensing cost.</p>
<p>We did a PoC to move the ARCAD installation into system pool (SYBAS) from the iASP and this instance was accessible across all iASPs. This in turn provided a saving of around <b>78,000 USD</b> </p>
<p>It was a challenging task (took us almost 3 months to implement the entire pipeline) but surely not impossible - and made us the pioneers in implementing DevOps on i-series while adopting agile principles. I would love to hear your views and recommendations if you have done similar work at your clients.</p>
