3 Tips For Mental Health as Cloud Engineer

Pakistan's First Oracle Blog - Mon, 2021-06-21 17:52

 It's simple. Our brain is our biggest asset when it comes to being a cloud or devops engineer. If you start loosing your mind or if its chaotic and unsound, then you won't be a cloud engineer for long for sure. Following are 3 tips to maintain your mental health as a cloud engineer.

1- You don't have to Learn it all 

You don't have to learn all hundreds of services offered by AWS, Azure, GCP, Ali baba, Oracle, etc. Don't stress about learning every devops CICD tool under the sun. You are not supposed to learn all there is in cloud w.r.t networking, compute, storage, databases, serverless, streams, ML, AI, integration, and other stuff. Stop falling into that bottomless chasm as you would never be able to get out of it. Just learn what's needed now. Just learn what your background is. Just learn what interests you. Just learn what gets the job done.

2- Don't take Cloud Job postings too seriously

One of the ways I was checking what's required by today's businesses in terms of skillset was to review cloud job postings. After going through the skills required, I was getting very depressed as the list was long. Then I started to realize that it was humanly impossible for anyone to possess all those skills in fullest. How can I be a full stack developer with rich networking background, having worked in true agile environment remaining abreast of CICD pipelines with a must docker and kubernetes 5 year experience, topped by some SQL and NoSQL database skills. Job posting just don't end there either. You have to know all those tools like DCOS, K8s, Maven, Ant, Gradle, TeamCity, Jenkins, Bash, Powershell, Python, Ruby, MongoDB, Kafka, Oracle, IAM, OKTA, AD, ELK, and plethora of other acronyms. Trust me, most of these job postings are unrealistic and they know it. If you foot even half of the bill in these job postings and are good at what you do, you should be fine. 

3- Keep Learning Enjoyably

Don't switch off and don't go to some remote monastery to meditate. We have made these careers after lots of hard work. We have to stay relevant in the industry. We have to pay mortgages and we have to provide for our family. What really stresses is the fear of lagging behind and going obsolete. We keep doing this cloud stuff because we enjoy doing it. What bothers is the endless list of things to learn. Just follow above 2 points and this stress should be very manageable, and then you can just focus on things which you really should be learning and what you enjoy learning. 

Happy learning and progressing.

Criteria that you can use when you are choosing a gambling agent

OraQA - Mon, 2021-06-21 10:00

Choosing a suitable online gambling agent has become very difficult these days. This is because many gambling agents are offering different games, enticing bonuses, and rewards that making a suitable choice becomes very difficult. With thousands of options available, you need to look for the best way, a method, or perfect criteria that you can use to choose the best gambling agent. Here are some of the tips to use

Check if the online gambling agent is available in your country

The first criterion is checking whether the online gambling agent is available in your country. This will help you avoid researching online gambling sites that don’t accept punters from your country or state. There are many agenjudi online terbesar that do not accept punters from other states and countries. The best way to figure out its boundary limits is through reading the terms and conditions. To be on the safe side, deal with online casinos within your country of residence.

Welcome bonuses and promotions

This may sound like a no-brainer but it is a very important factor when you are choosing a gambling agent. We all love free things and we also love promotions. That is the reason why gambling agents use promotions and bonuses to attract punters. With bonuses and promotions, you have an opportunity to win money without spending a dime from your pocket. Today, almost all gambling agents offer bonuses and promotions. Therefore, you should not settle for one that doesn’t offer bonuses and rewards.

Customer support

Another criterion is through checking the customer service of the gambling agent. How a gambling agent treats other punters is very important. Check whether an agent has customer support to help you and what other people are saying about different gambling agents.

Pakistan's First Oracle Blog - Thu, 2021-06-17 21:55

 Welcome to the next edition of weekly Cloud Vanity. There is so much razzmatazz about cloud that for a second we tend to think that every company is already on some sort of cloud. A recent study has found out that still only 35% of companies are in the cloud and rest of them are still thinking or planning to migrate. So still lot of opportunity there.

AWS:

Announcing the AWS Security and Privacy Knowledge Hub for Australia and New Zealand

Few things have changed the world more than the internet, and at the heart of the internet is the open source LAMP stack. LAMP, short for Linux, Apache, MySQL, and PHP, enabled developers to build new, interactive web experiences

Australian Commonwealth Government agencies are subject to specific requirements set by the Protective Security Policy Framework (PSPF) for securing connectivity between systems that are running sensitive workloads, and for accessing less trusted environments, such as the internet.

There are many factors that can affect critical environment (CE) infrastructure availability—the reliability of the infrastructure building blocks, the controls during the datacenter construction stage, effective health monitoring and event detection schemes, a robust maintenance program, and operational excellence to ensure that every action is taken with careful consideration of related risk implications.

The power of 5G, IoT, and real-time AI will unlock new and innovative services for enterprises across the world to accelerate their transformation toward Industry 4.0 as they evolve and adopt diverse new business models. 

Cloud and edge computing are coming together as never before, leading to huge opportunities for developers and organizations around the world. Digital twins, mixed reality, and autonomous systems are at the core of a massive wave of innovation from which our customers already benefit.

GCP:

As your organization evolves, the cloud can be a powerful tool to drive growth, improve efficiency, and reduce costs. In fact, the cloud is so powerful that most organizations find themselves running on multiple clouds

At its core, Data and Analytics allows us to make impactful decisions by deriving insights from our data. In the pursuit of making data meaningful, data scientists and engineers are often tasked with building end-to-end workflows to ingest, process and analyze data.

At Google Cloud, we believe moving to the cloud shouldn’t have to mean starting over from scratch. That’s why we’re on a mission to give you choices for how you run your enterprise workloads, including migrating and modernizing your Windows workloads. 

In times of significant disruption, organizations are faced with three choices: Retrench within legacy solutions, pause and do nothing while waiting for more data or different circumstances, or press ahead, potentially even accelerating to realize the desired outcome.

Our collective understanding of work—where it takes place and how it gets done—has been transformed over the last year.

Split Partition

Jonathan Lewis - Wed, 2021-06-16 06:33

This is a note I drafted a little over 5 years ago in response to a question on the Oracle developer forum about turning a simple heap table into a list partitioned table; but never got around to publishing it and now it’s not going to be of much benefit to most people because in 12c Oracle makes it very easy to handle the task of re-engineering partitioned tables online with a single “alter table” command.

But people do still run 11g, and the topic of changing, or repairing, a partitioning strategy has come up again very recently (more than once) in the context of 11g, so I thought I’d edit the draft and publish it.

There are, of course, many ways to start with a simple heap table and end up with a partitioned table, or start with a partitioned table in one state and end up with the table in a different state, and the method you choose may depend on various restrictions imposed from outside the database. One of the simpler strategies would be to “create table as select” to create a new partitioned table from the existing table and then rename the two tables – with possible variations such as exporting, creating an empty partitioned table, then re-importing ignoring creation errors.

Here’s a thought, though, that you might be able to take advantage if you need to enhance the partitioning of an existing partitioned table, but don’t have to re-partition all your data immediately. It’s an idea I came up with many years ago (long before the introduction of interval partitions) when a client had a daily partitioned table but had forgotten for a several months that they were supposed to do a regular “split partition” of the maxvalue partition in anticipation of future data arriving. They had a table with about 30 daily parititons, and one partition of about 500 days (18 months).

The first step, of course, was to split the big partiiton “above” the highest current value so that Oracle didn’t have to copy data into the resulting two partitions, so we could re-impose the regular splitting mechanism on the new, small, maxvalue partition. The follow-up step was to worry about splitting the one huge partition into daily chunks over the next few days or weeks.

The client’s initial thought was to write a simple pl/sql loop that generated and executed statements like:

alter table orders 
        split partition p20050907 
        at (to_date('02-Mar-2004','dd-Mon-yyyy')) 
        into (
                partition p20040302, 
                partition p20050907
        )
/

This would split the first day off the very large partition, then the next pass through the loop would move on one day and split off the next daily partition, and so on. While the code was simple it was not an efficient strategy – just think about the arithmetic:

To keep things simple, imagine we have 512 days in the intial partition and each day’s data is exactly 1GB. On the first split we read and write 512GB; on the second split we read and write 511GB, on the fird split we read and write 510GB … on the 511th split we read and write 2GB and the job is done. In total the loop reads and writes 511 * (512 + 2) / 2 = 131,327 GB.  (Average of 1st and last, multiplied by number of terms).

Now think about coding a more complex algorithm:

  • First split the big partition into 2 partitions of 256 days each, reading and writing 512GB;
  • Then split the two resulting partitions into a total 4 partitions of 128 days each, reading and writing 512GB (in total);
  • Then split the 4 resulting partitions into a total of 8 partition of 64 days each, reading and writing 512GB (in total)
  • On the 9th cycle you will have to split 256 partitions of 2GB each to produce 512 partitions of 1GB each, reading and writing a total of 512GB.

In total the algorithm reads and writes 9 * 512 = 4,604 GB which is about 1/30th of the simpler algorithm.

Conclusion

This example of splitting partitions is just one specific case of a general principle.

It’s easy to code up an “obvious” strategy without considering whether there might be a slightly more complex but vastly more efficient strategy. In many cases, of course, the difference in resource costs between the simplest and the most efficient strategies may not be worth the extra development and testing time, but when you start dealing with large data volumes it is always worth asking three questions:

  1. Do I have a reasonable idea of the resources that will be taken up by the obvious strategy
  2. Is the obvious strategy the only possible strategy
  3. Is it worth spending more human resources designing and testing a better strategy to save machine resources at run-time.
