Which of the following is the most important area of concern in cloud computing?
→Answers : →When your data travels over and rests on systems that are no longer under your control, you have increased risk due to the interception and malfeasance of others. →Perhaps the biggest concerns about cloud computing are security and privacy.
What are the most important parts of a micro service architecture to ensure reliability scalability and maintainability and finally a good quality of service?
In this chapter, the essential components of microservice scalability and performance are covered, including understanding the qualitative and quantitative growth scales, hardware efficiency, identification of resource requirements and bottlenecks, capacity awareness and planning, scalable handling of traffic, the …
How do you deal with back pressure?
Aside from scaling up your available compute resources, how you handle backpressure can pretty much be summed up with three possible options:
- Control the producer (slow down/speed up is decided by consumer)
- Buffer (accumulate incoming data spikes temporarily)
- Drop (sample a percentage of the incoming data)
What is one significant advantage of virtualization in datacenters?
Primary advantages of virtualization in data centers are: Cutting up on costs – Hardware is mostly the costliest asset of the Data centers. The perks of virtualisation are even higher as it is easy to maintain, consumes less electricity and there are even lesser occasions of downtime.
Which provides development frameworks and control structures?
Explanation: PaaS provides virtual machines, operating systems, applications, services, development frameworks, transactions, and control structures.
How do I start microservices?
Here are the key points to think about at that time.
- Keep communication between services simple with a RESTful API.
- Divide your data structure.
- Build your microservices architecture for failure.
- Emphasize monitoring to ease microservices testing.
- Embrace continuous delivery to reduce deployment friction.
How do you create a Microservice architecture?
Best Practices for Designing a Microservices Architecture
- Create a Separate Data Store for Each Microservice.
- Keep Code at a Similar Level of Maturity.
- Do a Separate Build for Each Microservice.
- Deploy in Containers.
- Treat Servers as Stateless.
- Fast Delivery.
- Migrating to Microservices, Part 1.
What Reactive back pressure?
Backpressure in Reactive Streams. Due to the non-blocking nature of Reactive Programming, the server doesn’t send the complete stream at once. It can push the data concurrently as soon as it is available. Thus, the client waits less time to receive and process the events.
How back pressure is created?
Engine exhaust back pressure is defined as the exhaust gas pressure that is produced by the engine to overcome the hydraulic resistance of the exhaust system in order to discharge the gases into the atmosphere. The term back pressure can be also spelled as one word (backpressure) or using a hyphen (back-pressure).
Are distributed systems inherently limited in scalability due to high latency?
This is illustrative of why distributed systems over a wide area may be inherently limited in their scalability, owing to the high latency of long-distance networks. For example, typical network latencies over the Internet can range from tens to hundreds of milliseconds.
Why are distributed computers so difficult to use?
Time delays introduced by the physical distribution of the compute systems and slow interconnection networks make the coordinated use of many distributed home computers impractical.
Is distributed computing a good fit for SETI?
Distributed computing efforts that utilize the Internet and individual consumer devices with “donated” compute cycles are a good fit for a subset of problems. For efforts such as SETI@home [2 ], which uses volunteers’ personal computers to look for evidence of extraterrestrial communication, it is an excellent fit.
Should you be storing sensitive personal data in your application?
Unless it’s critical to your business, there is no good reason to store sensitive personal data in your systems. Security is a complex matter, and if you are modifying your code everyday until you find your product market fit, it will break. Assume that anybody ill-intended could breach your application if they really wanted to.
