Is it a big mistake to think that "everything will be fine if we move it to the cloud"? The importance of the IT veteran "mainframe"
Hello, I'm John, a blog writer who explains AI and technology in an easy-to-understand way. Today I would like to talk about a very important lesson in the world of technology: "New is not always best." In particular, I would like to talk about the relationship between the "cloud," which we hear a lot about these days, and the computer called the "mainframe," which continues to support our lives behind the scenes.
The failure of one large company: "Cloud is everything" leads to tragedy
This is a story from a famous financial institution. The company declared, "The cloud is here!" and set out a "cloud first" policy, under which all new projects would be carried out on the cloud. They tried to migrate the entire trading system, which had been the heart of the company and operated stably for many years, to the cloud.
This decision caused a team of mainframe experts who had been protecting the system for many years to sound the alarm. "This critical processing may not be suitable for the cloud." However, at the time, the cloud boom was in full swing. Unfortunately, their voices were not heard.
A year into the transition, problems continue to arise.
- Cloud usage fees have skyrocketed beyond expectations.
- Complaints flooded in about degraded system performance and slow service during peak times.
In the end, the company had to call back its mainframe engineers and move key operations back to the mainframe -- a painful tale of failure that would have been a shame had the company listened to experts from the start.
First of all, what is a "mainframe"?
You may not be familiar with the term "mainframe." To put it simply,A huge, powerful computer used by banks, governments, insurance companies, etc.It has a level of power and reliability that cannot be compared to the computers and smartphones that you use every day.
For example, when we withdraw money from an ATM or make a purchase with a credit card, it is the mainframe that processes the enormous number of transactions instantly and without error. They are truly the "unsung heroes" that support the infrastructure of society.
On the other hand, the "cloud" refers to computer power and data storage space that can be easily accessed via the Internet. Its appeal is the ease of being able to rent only what you need.
Are mainframes outdated? No, they're evolving!
You may have the impression that "the cloud is the latest and the mainframe is old," but that's a misconception. In fact, the mainframe is still evolving.
Large companies like IBM continue to invest in aligning their mainframes with modern technologies. For example,API (API: an "interpreter"-like mechanism that connects different software programs)We are introducing new cloud services to enable the mainframe to communicate smoothly with new services in the cloud and to adopt the latest development techniques.
Mainframes are no longer museum pieces; they're still in use today and getting smarter.
The optimal solution for the future: the "hybrid" approach
So, which is better, the cloud or the mainframe? This question itself doesn't really mean much. The important thing is toThe right person in the right place" and use them appropriately.
A good analogy to cooking might be to think of it this way: a powerful oven (the mainframe) is ideal for roasting a big chicken, and a microwave (the cloud) is convenient for just reheating something. Trying to do everything with just one doesn't work.
The smart IT of the future will be one that combines the best of both worlds.HybridIt is.
- Mainframe Advantages: Reliable processing of large volumes of transactions, ironclad security, and high reliability
- Cloud Advantages: Agility to rapidly develop new services and scalability to roll out services around the world
In this way, by leveraging each other's strengths, companies can create truly valuable innovations.
What's important is respect for technology and an open culture
At the heart of this story is a question of technology culture. Great organizations don't just jump on the latest technology trend. They bring mainframe experts, cloud experts, and data scientists together at the same table, sharing ideas and respecting each other.
If we label something as "old technology" and disregard experts, we risk losing the valuable knowledge and stability that the technology has accumulated over the years.The right tool for the job" This mindset will be essential in the future.
This story shows us the danger of blindly following trends in the world of technology. It reminds us that it's important to have a balance between the curiosity to look at new things and the wisdom to respect what's proven.
