From cloud to multi-cloud

From cloud to multi-cloud

ICT-business is the most innovative sector in the field of business. The reason for that innovation and hectic way to make things is that the software business is handling the virtual tools, what are not need physical investments. Every person in the world, who has the right skills can try those things even at home, and that means the new type of solutions are created all the time, and this thing makes computer business so innovative and interesting working area. Trends in that are changing extremely fast, and when somebody creates something, the competitors must make something better.

Multi-cloud is the trend of computing. That means that the person is connected with the Internet with multiple cloud-based systems, what is making the database operations more flexible and sophisticated. In the multi-cloud architecture data processing systems are all connected to the network all the time, as they could be in single-cloud architecture. But the main idea of this kind of systems is that the clouds are operating like single computers.

And the cloud is computing service, what the user cannot control or see. In the cloud the thing, what the user gets is the application, and that means that they cannot see, what kind of server systems runs that service. Cloud means every process what happens in the cloud is distributed to many servers, and the databases would also be in multiple places, even if they seem to be one. 

The name"cloud" means that the service is the thing, what the client gents, and that is the only thing, what that person needs, and the situation is, that the operating system of the service and technical details of the servers are hidden from end-user. First, this technology has been used as the hard calculations, but then it has been grown to use with other solutions.

The benefit of that kind of system is, that the service is guaranteed even in the server would be destroyed by some kind of accident. In the cloud service, the most important thing is that the service would continue without errors in every case, and the normal service routines must be done without disturbing the service.

That means that when the operating system updates would run to the server, the updates would download to another server, and then the service will swap to run under that server, and then another server will be updated. In net-based service, every system is actually at least doubled, because that would make the service sure in the special situations. And in multi-cloud, every data-handling unit is cloud, which means that there are multiple computers for each service.

Could this be the thing, that some people don't want you to know about zombies?

Could this be the thing, that some people don't want you to know about zombies? The simplest way to control zombies, which are made by using tetrodotoxin, which is called "zombie poison" is to use the automatic dispenser, which is normally used in diabetes treatment. In this case, the dispenser would be loaded by using tetrodotoxin. If the level of this poison is right, the person would be totally under the control of other people. And if the system cannot detect this poison there is a possibility to make the laboratory experiment when the staff will follow the decrease of the tetrodotoxin, and then the system can use a simple clock, which will inject poison to the body of a victim after a certain time. This would be an effective tool in the hands of military and counter-terror operators. Those zombies can be captured enemy operators, who will send back, and then they just kill their ex-partners. By using genetically engineered bacteria could be possible to create t...

The cyborg lichen can be one of the most exotic visions of what the high-tech civilization might look like.

.     The cyborg lichen can be one of the most exotic visions of what the high-tech civilization might look like. Above is the image of the nano-submarine. There is introduced an idea, that this kind of system would equip with living neurons, which makes it like some kind of artificial bug or mosquito. The idea is that the robot can take the nutrient by using the robot tube, which acts like a proboscis. The neurons can get nutrients and the rest of the machine can use small fuel cells or the energy to that system can deliver by using the radio waves. Futurologists are thinking about the ideas, what the hybridization of the neurons and machine would look like? Could the hyper-technical civilization look like the group of midget submarines? Those submarines might take nutrients for the neurons, what is living in them. The purpose of the midget submarines, which might be size less than a couple of millimeters would maximize the survivability of the neurons. One of the most intere...

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...
