We do not mean the nitty-gritty details of TCP/IP, DNS, sockets, or other such protocols. Hard real-time distributed systems development is bizarre for one reason: request/reply networking. They look kind of like regular computing, but are actually different, and, frankly, a bit on the evil side. Hard real-time distributed systems are the same. Bizarro looks kind of similar to Superman, but he is actually evil. In one plot line from the Superman comic books, Superman encounters an alter ego named Bizarro who lives on a planet ( Bizarro World) where everything is backwards. First, let’s review the types of distributed systems. Before diving into these techniques in detail in other articles, it’s worth reviewing the concepts that contribute to why distributed computing is so, well, weird. What’s worse, it’s impossible always to know whether something failed.Īcross The Amazon Builders’ Library, we address how AWS handles the complicated development and operations issues arising from distributed systems. In addition to the typical computing failures most engineers are used to, failures in distributed systems can occur in many other ways. Independent failures and nondeterminism cause the most impactful issues in distributed systems. Distributed computing is also weirder and less intuitive than other forms of computing because of two interrelated problems. As the systems quickly grew larger and more distributed, what had been theoretical edge cases turned into regular occurrences.ĭeveloping distributed utility computing services, such as reliable long-distance telephone networks, or Amazon Web Services (AWS) services, is hard. Then as now, challenges with distributed systems involved latency, scaling, understanding networking APIs, marshalling and unmarshalling data, and the complexity of algorithms such as Paxos. However, even in 1999, distributed computing was not easy.

When I started at Amazon in 1999, we had so few servers that we could give some of them recognizable names like “fishy” or “online-01”. 'What I heard you say was.The moment we added our second server, distributed systems became the way of life at Amazon.

Say things in ways that will be easy to hear - Make sure you understand what is being said.

Be optimistic - remember the good things about this person try not to generalize criticisms (do not use 'always' or 'never').

Stay friendly - work up to the more difficult topics don't make negative comments.

Be Realistic - change takes time appreciate the small steps of improvement.

Problem-solving training changes communication skills and aids in creating interpersonal relationship satisfaction. Improving Communication In Your RelationshipsĬommunication problems are the most common reason for seeking counseling, accounting for 40% of all counseling issues.

Acknowledge progress to the other person.

Focus on what you want, not on what you don't want Your job is to problem-solve, not to simply take on other people's problems.

Don't let the other person's problem become your problem.

Once you have done what you reasonably can do, don't beat yourself up if the outcome is not totally satisfactory to each of you.

You are not able or responsible to solve all problems.

Provide the opportunity for everyone to “save face.”.

Ask what he or she has done to try to resolve the problem.

As much as possible, do so collaboratively.

Problems are only opportunities in work clothes.

Make the problem something that you are both working on collaboratively to solve.

The problem is usage of room time, not that one roommate is a jerk who plays music too loudly, and the other is a jerk who sleeps too much.

Reframe the problem so that it is not personal.

Encourage the person to talk – this provides you more understanding of the “real” issues involved and often provides clues for possible solutions.

Clarify the expectations of the interaction.

Physical cues – use head nods, eye contact, open body posture this lets the listener know that you are listening.

Summarization – listen for themes or main points.Clarification – ask questions to clarify if you are unsure.(Vent later with a friend or colleague if you need to.) Recognize that your role is to be calm and objective. Expect that difficult situations will take time to resolve – if you feel rushed, ask to meet at a later, specific time.Meet privately – having an audience causes more defensiveness.Here are some tips for dealing with difficult people and difficult situations: Part of your success and happiness in college depends on your ability to effectively negotiate problems. College life involves frequent interaction with people in a multitude of situations, ranging from getting along with roommates to negotiating group projects.
