Programmers.io is an IBM certified, US-based software development company that has an excellent software development team, which has years of experience in software development with multiple platforms. We offer affordable software development services in multiple platforms such as IBM i/AS400/RPGLE/COBOL, Dot Net, PHP, Angular 2+, Node.js etc.
AS400 is still considered as a pricey relic from a bygone era. As technology is enhancing day by day and the cost of cloud hosting is decreasing, organization have declared AS400 as outdated. The retirees are creating a hole in the market which is filling at a very low speed because the youngsters are not looking at IBMi or RPG as a career option. Due to this, organizations are afraid of the lack of IT support and are hesitating in relying on the technology.
But is this really true? No.
AS400 may be an old IBM series but it has evolved overtime and is successfully used in many big technology organizations. The companies that depend on mission critical systems and complex ERP systems, for them AS400 i series has proved to be of great help and support. People think that as IBMi or AS400 is considered as a legacy technology therefore there would be lack of IT support and proper guidance. But this perception is completely denied by some of the best organizations of the world. Hiring RPG developers from reliable third party sources and maintaining your own team with their help is the feasible option that companies are choosing without hesitation. This approach has helped them work with talented IBMi programmers keeping their system strong and profitable.
Companies relying on IBMi development
AS400 servers are still fairly common. According to iDatalabs, IBM hardware is used by about 10.1% of companies, making it the second most popular type of server after HP servers i.e. 24%.
However, these figures cannot be said as exact because IBM hardware supports other, more popular operating systems, but it’s unclear what proportion of the users on those systems are actually using the IBM architecture.
AS400 is popular in high-tech, core, mission critical industries, such as manufacturing, computer software, logistics etc. Many big American companies are using AS400 extensively and it has a tough grip over midmarket companies (38%), but is used across organizations of all sizes.
Companies like Robert Bosch and CVS Health earn a lot of profit and generate significant revenue. They opted to install IBM Power systems to run their IT systems, depending on their performance, reliability and scalability.
Why is IBM Power system still the most trusted?
Although the AS400 series has made its space among the legacy technologies but still it is one of the most trusted server series. Why? The answer is right below:
Preserving the AS400 performance and reliability: The biggest reason why the latest IBM iSeries are extensively used by the companies round the globe is the power of the AS400 series. The IBM AS400 was built with robust hardware redundancy. These features are still preserved in the IBM iSeries that make it extremely high-performing, with CPUs that are 3-5 times more powerful than others. For applications that require extremely high performance and low downtime and for many other hard core applications, IBM power systems are reliable.
Availability AS400 options: Opting for AS400 or IBM Power systems is useful for any type of organization. From inexpensive, entry-level systems to high power, redundant servers, IBM has solution for every business that is scalable and secure. The IBM iSeries also support multiple operating systems, such as AIX, IBM i, SUSE and RedHat Enterprise Linux.
Businesses have relied on AS400 systems since the inception and have grown with it over the years. Organizations using the system already know how useful, powerful and efficient these systems are. Especially for companies that deal in very critical, core tasks they need highly efficient, secure and competitive systems/servers for data storage and functioning. IBM Power systems today have overcome every other option because of their extraordinary features, reliability and scalability.
In this article, we will be discussing an algorithm that helps us analyze past trends and lets us focus on what is to unfold next so this algorithm is time series forecasting. In this analysis, you have one variable -TIME. A time series is a set of observations taken at a specified time usually equal in intervals. It is used to predict future value based on previously observed data points.
