Many believe the mainframe is dead as newer, easier technologies like cloud computing have come to the fore. However, this is a myth as the power a modern mainframe can deliver is better than anything else, writes BRIAN PEREIRA of Digital Creed.
Once upon a time, there were huge, monstrous computers used in large organizations to process data. They stored data on a bank of magnetic tapes that looked like your grandpa’s Grundig or Akai reel-to-reel tape recorder. There was no mouse or color LCD screens then; you had to type cryptic commands (and know them by heart). And the output would appear on “terminals” — displays with green screens. The mainframe central processing units looked like large cupboards in an office, but later, they took on sleek designs. Though IBM was the leading manufacturer of mainframes in the ’50s, ’60s, and ’70s, there were others who made these machines: Burroughs, UNIVAC, NCR, Control Data, Honeywell, General Electric and RCA (called the seven dwarfs). There were a bunch of companies that made applications for mainframes: BMC Software, Compuware, CA Technologies and others. At one point of time, mainframes were the major source of revenue for IBM and the seven dwarfs. When the client-server era arrived in the 1990s, the mainframe business started to decline. So IBM and others had to restructure their businesses and turned their attention to PCs, servers, consulting and services. And then came the era of cloud and data centres. So whatever happened to the mainframe computer and the industry that created applications and services on the mainframe platform?
IBM continues to make mainframe computers today, under the Z-systems portfolio (z13s mainframe shown in the image). But who uses mainframes today? And are they still relevant?
Malav Kapadia, Global Director & Head of Indian Outsourcing Partners, BMC Software said, “We started our business in 1980 and focussed on mainframes. Till 1995 about 95 – 96 per cent of our revenue came from the mainframes business. It is about 30 per cent now and is still a large chunk of our portfolio.”
BMC Software has annual revenue of $2 billion so 30 per cent of that is still quite significant. The company offers solutions for mainframe management and cost optimisation.
It also offers non-mainframe solutions ranging from Helpdesk to real-time monitoring solutions, cost optimisation/management, mobile and automation solutions.
In India, BMC works with large enterprises directly or indirectly through system integrators like TCS, Wipro, HCL, Cognizant, L&T Infotech, and Tech Mahindra.
Kapadia says mainframes are still used today to process 95 per cent of the transactions in the banking, insurance, airline and retail industries.
“While the myth is that mainframes are legacy, it continues to grow and thrive. The fire power that a mainframe can deliver is better than anything else out there. The number of transactions that they can handle, the load and the real-time results they deliver is still the best. We have a big relationship with IBM and will continue to support them on mainframes,” he says.
It’s no wonder that mainframes are also called “big iron” systems. People in the industry say that mainframes continue to deliver ROI or return on investment.
Of course, mainframes have evolved today and have advanced operating systems, more memory, disk drives and GUIs. They also work in the cloud. But the fundamentals remain the same: they sill run applications like COBOL programming language, FORTRAN programming and DB2 (database). COBOL and FORTRAN programmers are also in demand as such programming skills are rare.
So mainframes continue to thrive in the age of cloud and datacenter, and will continue to be around for many more years.
What is a Mainframe?
According to Wikipedia, Mainframes are computers used primarily by large organizations for critical applications, bulk data processing, such as census, industry and consumer statistics, enterprise resource planning, and transaction processing.
The term originally referred to the large cabinets called “main frames” that housed the central processing unit and main memory of early computers. Later, the term was used to distinguish high-end commercial machines from less powerful units. Most large-scale computer system architectures were established in the 1960s, but continue to evolve.

Auto rivals team up for connected car demo
Rivals BMW, Ford and Groupe PSA, maker of Peugeot and Opel cars, have teamed up with the 5G Automotive Association (5GAA), Qualcomm Technologies and Savari for Europe’s first live demonstration of C-V2X direct communication technology operating across vehicles from multiple auto manufacturers.
The live demonstration also featured a live showcase of C-V2X direct communication technology operating between passenger cars, motorcycles, and roadside infrastructure. C-V2X is a global solution for vehicle-to-everything (V2X) communication in support of improved automotive safety, automated driving and traffic efficiency.
The demonstration exhibited the road safety and traffic efficiency benefits of using C-V2X for Vehicle-to-Vehicle (V2V) collision avoidance, as well as Vehicle-to-Infrastructure (V2I) connectivity to traffic signals and Traffic Management Centers (TMC). C-V2X was operated using real-time direct communications over ITS spectrum and demonstrated its ability to work without cellular network coverage, and underscores its commercial readiness for industry deployment as early as 2020. Superior performance and cost-effectiveness compared to other V2X technologies, along with forward-compatibility with 5G, make C-V2X direct communications a preferred solution for C-ITS applications.
Six demonstrations were shown including: Emergency Electronic Brake Light, Intersection Collision Warning, Across Traffic Turn Collision Risk Warning, Slow Vehicle Warning and Stationary Vehicle Warning, Signal Phase and Timing / Signal Violation Warning and Vulnerable Road User (pedestrian) Warning. The vehicles involved included two-wheel e-scooters provided by BMW Group, and automotive passenger vehicles provided by Ford, Groupe PSA, and BMW Group, all of which were equipped with C-V2X direct communication technology using the Qualcomm® 9150 C-V2X chipset solution. V2X software stack and application software, along with roadside infrastructure, were provided by industry leader, Savari.
C-V2X is globally supported by a broad automotive ecosystem, which includes the fast growing 5GAA organization. The 5GAA involves over 85 global members comprised of many leading automakers, Tier-1 suppliers, software developers, mobile operators, semiconductor companies, test equipment vendors, telecom suppliers, traffic signal suppliers and road operators.
Cellular modems will be key to the C-V2X deployment in vehicles to support telematics, eCall, connected infotainment and delivering useful driving/traffic/parking information. As C-V2X direct communication functionality is integrated into the cellular modem, C-V2X solutions are expected to be more cost-efficient and economical over competing technologies, and benefit from accelerated attach rates. C-V2X direct communication field validations are currently underway in Germany, France, Korea, China, Japan and the U.S.
C-V2X currently stands as the only V2X technology based on globally recognized 3rd Generation Partnership Project (3GPP) specifications, with ongoing evolution designed to offer forward compatibility with 5G. C-V2X also leverages and reuses the upper layer protocols defined by the automotive industry, including the European Telecommunications Standards Institute (ETSI) organization. C-V2X includes two complementary transmission modes:
- Direct communication as shown in this demonstration for V2V and V2I use cases
- V2N network communication, which leverages mobile operators for connectivity and delivers cloud-based services, including automated crash notification (ACN, as mandated by eCall), hazard warnings, weather conditions, green light optimal speed advisory (GLOSA), parking spot location, and remote tele-operation to support automated driving, to name a few.
“This demonstration builds on the successful C-V2X showcase we organised with our members Audi, Ford and Qualcomm in Washington DC in April, said Christoph Voigt, Chairman of 5GAA.
“We are excited to witness the growing momentum behind this life-saving technology and to see our members working together to deploy C-V2X, and to make it hit the road as soon as possible.”
“The BMW Group introduced the first C-ITS use cases already in 2013 with the market introduction of the BMW i3. Today most of envisaged C-ITS use-cases are already institutionalized. With the implementation of C-V2X, the BMW Group accomplishes the last set of the puzzle with a practical path to C-ITS showing quick benefits,” said Christoph Grote, Senior Vice President Electronics, BMW Group.
“With its ability to safely and securely connect vehicles, along with its evolution into 5G, C-V2X is integral to Ford’s vision for future transportation in which all cars and infrastructure talk to each other,” said Thomas Lukaszewicz, Manager Automated Driving, Ford of Europe. “We are very encouraged by preliminary test results in Europe and elsewhere which support our belief that C-V2X direct communications has superior V2X communication capabilities.”
“We’re moving forward with seamless communication between cars and their environment for enhancing road safety, as well as our customers’ safety,” said Carla Gohin, Group PSA’s Vice President for Research and Advanced Engineering. “Following the first European C-V2X direct communications demonstration we hosted with Qualcomm Technologies last March, we’re pleased to work with leading automotive and technology companies today to highlight that C-V2X interoperability is a reality.”
“This demonstration of interoperability between multiple automakers is not only another milestone achieved towards C-V2X deployment, but also further validates the commercial viability and global compatibility of C-V2X direct communications for connected vehicles,” said Enrico Salvatori, senior vice president & president, Qualcomm Europe and MEA. “We look forward in continuing to work alongside leaders in the automotive industry, like the 5GAA, BMW Group, Ford, Groupe PSA and Savari, to help advance the automotive industry’s shift towards a safer, connected and more autonomous future.”
“As one of the V2X pioneers, our company is extremely pleased to continue to help enable the next step in the V2X revolution that we helped start back in 2008,” said Ravi Puvvala, CEO of Savari. “For the last year and a half, the Savari team has worked diligently alongside the dedicated C-V2X engineers in the 5GAA partnership. The resulting string of increasingly impressive demonstrations is continuing to convince the world that C-V2X will soon be deployed around the world.”
Win a Poster Heater with Gadget and Takealot.com
This winter Gadget and Takealot.com are giving away three Poster Heaters, which look like posters but become heaters when you plug them in.
Three Gadget readers will each win a unit, valued at R550 each. To enter, follow @GadgetZA and @Takealot on Twitter and tell us on the @GadgetZA account how many Watts the heater consumes.
What’s the big deal about these heaters? Many of us are struggling to keep the balance between soaring electricity costs and the need to keep warm this winter.
However, the recently launched Poster Heater by EasyHeat and distributed in South Africa by Takealot.com is not only one of the most cost effective electric heaters currently on the market, it is also easy to setup and use.
As the name indicates, it is a poster similar to one you would hang on a wall. But, plug it in and it turns into a 300 Watt heater. The Poster Heater isn’t designed to heat hallways or large rooms, but rather smaller ones like a bedroom or a baby’s nursery or a dressing room.
It uses radiant heating, which means that it heats up in a couple of minutes and the heat is directed at the objects or people around it, quickly taking the chill out of the air and providing a comfortable ambient temperature.
The other advantage of radiant heating is that it doesn’t dry out the air like infrared or gas heaters. Users also don’t have to worry about their children or pets getting too close to it because, even though it gets hot, it can be touched.
To enter the competition follow the steps below:
Competition entry details:
