Our transportation has not changed over 100 years. We have been using trains, cars, bikes, planes, and even horses. Hyperloop is basically a new concept and is being considered as the fifth mode of transportation. So, what actually is a hyperloop?

How doeas Hyperloop works?

Hyperloop consists of pod or capsule which is used to transport people or goods that is operated in a sealed tube at near vacuum environment. The pod floats over the surface of the tube by magnetic levitation. So, there is no friction.No air friction means the pod traveling at an average speed of 900 kmph with a top speed up to 1220 kmph. The system is powered by a solar panel so it is extremely energy efficient. As a matter of fact, the hyperloop generates more energy than it consumes as a closed system.

The concept of hyperloop backs to 1909 when rocket pioneer Robert Godard purposed similar concept for a vacuum train. However, it was recently brought to light by a technopreneur Elon Musk. When he was stuck in LA traffic for his meeting, he thought for the concept for that fifth mode of transport as we know as ‘hyperloop’.In 2013, he drafted the blueprint for the Hyperloop, he then put the challenge for developing this to the engineering community at a competition.

The test for the Hyperloop is being done in a 500-meter Devloop track in Nevada desert. There are three companies currently involved in the development of the Hyperloop technology and bring it to real life.

  • Hyperloop technologies
  • Hyperloop transporter technology Inc.
  • SpaceX

Recently Richard Branson and his Virgin Group has also joined to invest in hyperloop.

Science behind Hyperloop

The passenger capsule and freight capsule are propelled by an electromagntic motor in a low-pressure hyperloop tube. The low pressure minimizes the friction due to air. But, even a small amount of air in the tube can cause a problem. Due to the Kantrowitz limit, at lower speeds, there is enough space between the pod and the tube for the air to pass through. But, as the speed increases, this reaches a limit, the pod begins to push a large volume of air ahead of it. This cause the speed of the pod to decrease immediately. This can be fixed by using the compressor fan in front of the pod and redirects it to the back for the additional thrust or to the air bearing to levitate to the pod on a cushion of air.

Why Hyperloop?

Costs

Hyperloop is much cheaper to build. The cost to build is cheaper by 4 billion dollars for the same distance as compared to the purposed California high-speed railway system that will be costing around 10 billion dollars. So, the ticket can be as low as 25 $ per trip for LA to San Fransico taking only 30 minutes for the travel.

Safety

The Hyperloop is much safer than other modes of transport including air transport. The tubes stand over the pillar- these pillars have a lower footprint as it is above the ground. In the case of an earthquake, each tube track can sway.

Freight Transport

The Hyperloop will transform freight transportation as it allows the fastest delivery of raw materials to the manufacturing units at a very low time. This will increase the productivity and efficiency of the industrial complex.

Moreover, Hyperloop will also transform our migration phenomena as people can reach the big cities at a very less time. They can choose to live in places with low housing cost and cheaper cost of living.

Some critics claim that the experience in hyperloop can be unpleasant and frightening as the passengers are riding in sealed and windowless capsules at a lower pressure environment. The passengers have to experience significant acceleration forces and level of noise at near sonic speed. The noise due to air being compressed vibrations and joltings will be significant. At such speed of Hyperloop, a passenger will also be experiencing lateral G-force at curves of the tube. Some also literate the situation as “an elephant sitting on the chest.”Musk has told that the route will be decreased to be maximum of 0.5 G.

The Hyperloop is still in the development phase. There are several problems that need to be solved before bringing to the general public. However, the potential is huge and implementation is real. Because of huge prospect, many countries have shown great interest in developing Hyperloop in their cities including India, China, UAE, Russia, South Korea, and Europe.No wonder, Hyperloop experience will be really fascinating.

The term DevOps has been derived from the combination of two words, ‘Development‘ and ‘Operation.’ In the world of solos’, the concept of DevOps is a disruptive technology that brings the culture of collaboration. Of Course, the inception of DevOps came out of frustration due to the division between the developer team and operation team.

The DevOps movement always gives preference over the collaboration between the people than processes and tools. In DevOps philosophy, outcomes start appearing from ‘Day One.’ People are working on the changes rather than stressing over a plan.


In the past developing trends, the team used to works separately for a while, and the last task is accomplished by merging the changes. This made merging the changes made on the code ‘a headache’ and also resulted in bugs being accumulated for an extended period without being corrected. The final result was slowing the updates and extension of delivery time.

How does a simple DevOps scenario works?

Before initiating a project, developer, tester and operation team meet and discuss on how to create working software that could be readily deployed. After finalizing on the context and working module, the developer team each day deliver with a new code. The working module is then pushed to a central repository using version control system tools like Git. Before performing each commit, the developer might want to run the local unit tests on the code as an extra verification procedure before to integration.

Continuous Integration (CI) tools automatically build and runs unit tests on new code changes to immediately surface any errors. If the particular module is successfully tested over the test server, then deployment can be performed through a single button click.

Advantages of DevOps:

  • Through the concept of microservices and continuous delivery, it is easier and faster to prepare a release update. Thus, it helps the business grow more efficiently.
  • The automation tools used in release process helps to deliver innovation and improve the product more frequently rapidly.
  • The system and application become more reliable and stable due to the practice of continuous integration (CI) and continuous delivery (CD) before being presented to end-users.
  • The scalability is higher due to the concept of microservices and API design.

DevOps Practices:

Here are the top development operation practices you need to follow according to your programming skills.

Continuous Integration:

Continuous integration (CI) is a DevOps practice where the programmer merges their build codes to the central repository. The version of the system is committed to the repositories like Git where after the codes are automatically built and test, and further can be pushed to the production servers. The merging is done regularly, and each version of the build is updated based upon the test result.

Continuous Delivery:

You can’t just ask customers what they want and then try to give that to them. By the time you get it built, they’ll want something new.

Steve Jobs

CD completely redefines how a product is delivered to end users. Each time developers present an application module, it can be automatically built, tested and deployed to the end user through a simple ‘push‘ button. Any feature addition and change just get simpler.

MicroServices:

A monolithic application design always slows down the application development as well as for making changes to the existing design. Because all the services are tightly coupled and always create a dilemma on what be the impact on the portion of the application when change is made on other portion.

The basic principle of microservice architecture is to divide a single application into multiple services. Each of the services has its own scope and any communication necessary required between the services is made through API ‘calls’.

Blue/Green deployment:

The basic concept of blue/green deployment is to have two identical production environment where blue is ‘live‘ and green is ‘idle‘. This greatly reduces the application downtime. As a new application is deployed, it is initially deployed to the ‘green’ server. After the successful testing on the green server, then all the required IP is pointed to the ‘green’ server and it goes ‘live’. If any problem occurs, the switch can be turned back to the ‘idle’ one to direct all the traffic to it.

However, this approach might not be feasible if cost is the factor as well as database-dependent application.

Chaos Monkey:

This practice has been invented and popularized by Netflix.”What will happen when a monkey enters a Data Center? A monkey may randomly rip off the cables and may kick the routers and servers. “This is the situation a DC operation team must be able to face to make a system resilient. Netflix has developed a program that randomly to shut down a server and IT managers need to mitigate this situation by keeping the system operational even without that server.

A developer always thinks of making a system more agile while an operation team want the system to be more stable. So, a delicate balance is required to maintain a good relationship between a developer team and operation team otherwise it might blow up. DevOps culture with the help of numerous automation tools can greatly add value to the development to deployment phase and satisfy the end users on time.

Last but not least, the DevOps is not a magic stick and transformation doesn’t happen overnight. By properly understanding the values of DevOps and making small incremental changes, we can embark on DevOps journey right away.
