As the process of cloud modernization becomes ever more complex, there is an even greater need to embrace the emerging role of cloud architect to accelerate transformation. One thing that’s imperative is modernization and digitization cannot be achieved alone. Partners are integral to the process and a necessity if organizations want to achieve faster, greater, and more scalable modernization. .

When I worked at Google, fleet-wide profiling revealed that 25-35% of all CPU time was spent just moving bytes around: memcpy, strcmp, copying between user and kernel buffers in network and disk I/O, hidden copy-on-write in soft page faults, checksumming, compressing, decrypting, assembling/disassembling packets and HTML pages, etc. If data movement were faster, more work could be done on the same processors.

TL;DR : To serve users at the 75 th percentile ( P75 ) of devices and networks, we can now afford ~150KiB of HTML/CSS/fonts and ~300-350KiB of JavaScript (gzipped). This is a slight improvement on last year's budgets , thanks to device and network improvements. Meanwhile, sites continue to send more script than is reasonable for 80+% of the world's users , widening the gap between the haves and the have-nots.

This is a synthesis of several recipes that I’ve modified over the years. I usually make a cake for the holidays. Growing up my mother made what she called a Dundee Cake, a round fruit cake with almonds on top. She would make it a month before, and soak brandy into it. My version avoids wheat and dairy, I use honey rather than sugar and I soak the fruit in spirits before I make it, then it’s good to eat a few days later.

One of the routine operations when administering PostgreSQL is periodic updates to the database system’s architecture. PostgreSQL does a good job of allowing one to update a schema, add types, functions, triggers, or alter a table by adding and removing columns and updating column data types, etc., in a reliable manner. However, there is no built-in mechanism to help identify the differences, let alone generate the necessary SQL, to accomplish updates in an easy manner from the development

Let’s say you have highload instances. How do you monitor them? There are a lot of servers with 100, 200… 500+ nodes. How can we collect, check, and analyze metrics from all these servers? How can we understand what and where something happened? Scroll, scroll, scroll… down? That was the task that we faced at Percona and successfully resolved.

PostgreSQL manages database access permissions using the concept of roles. A role can be either a database user or a group of database users, depending on how the role is set up. Roles can own the database objects and assign privileges on those objects to other roles to control who has access to which objects. Furthermore, it is possible to grant membership in a role to another role, thus allowing the member role to use privileges assigned to another role.

A career as an Automation Tester has a lot of benefits, especially since it is a growing career field and is required by almost every firm. Automation testing helps a company reach a wide variety of audiences, doing it efficiently without using much time or money as it replaces manual testing though not entirely. It also helps do the testing of large-scale projects more effectively.

I wrote this post on MyRocks because I believe it is the most interesting new MySQL storage engine to have appeared over the last few years. Although MyRocks is very efficient for writes, I chose a more generic workload that will provide a different MyRocks use case. The use case is the TPC-C benchmark but executed not on a high-end server but on a lower-spec virtual machine that is I/O limited like for example, with AWS EBS volumes.

Patroni is one of the most used high availability (HA) solutions with the PostgreSQL database. It uses a Distributed Configuration Store (DCS) to keep the configuration in a centralized location available for all nodes making it an easy-to-use and reliable HA solution available in the market today. On the other hand, pgBackRest is a backup solution that helps in taking not only the FULL backup but also incremental and differential backup.
