Maximizing spectrum efficiency is a challenge that operators have wrestled with for decades. And the challenge of optimizing spectrum planning and management is only magnified as networks become faster and more complex. Operators with a well thought-out plan can avoid significant waste and inefficiency in the network. Wavelength division multiplexing was originally constrained to a fixed grid, first at channel widths of 100GHz, and then, as lasers improved, at 50GHz.

Most interactions with a web application occur at the browser. Users search items, fill forms, create shopping carts, log into their profiles, and perform many other tasks. Unit tests are great, but nothing beats testing an application by interacting with the user-facing frontend. In this tutorial, you will learn and demonstrate how to write tests for the browser using Puppeteer . You will then take this a step further by automating the testing process in a continuous integration flow.

I worked at Google for six years. Internally, you have no choice — you must use Kubernetes if you are deploying microservices and containers (it’s actually not called Kubernetes inside of Google, it’s called Borg). But what was once solely an internal project at Google has since been open-sourced, and has become one of the most talked-about technologies in software development and operations.

When you issue a query to SQL Server or Azure SQL, it internally tries to optimize a query plan through calculations such as whether to use an index. Much of SQL Server’s query plans are based on its best guess of what will happen at run time when your query executes. Even when SQL Server guesses right, as your data changes (especially as the volume of data increases), optimal plans can end up performing so poorly, they can drag your whole system’s performance down.

Creating a new Host within the Icinga 2 configuration files is fairly easy. Basically you only have add an object of the type “Host” to a config file and reload Icinga 2. Doing the same with Icinga Director is even easier, you don’t even have to bother with terminal editors and configuration files. However, what sounds so easy for an experienced user may not be so obvious for beginners.

According to AWS, “Creating a software system is a lot like constructing a building. If the foundation is not solid, structural problems can undermine the integrity and function of the building.” This is especially true when it comes to the cloud. If an organization doesn’t effectively oversee key areas of its foundation, it’s likely the result is not going to be successful. When it comes to cloud management, we look at it through the lens of the AWS Well-Architected Framework.

We are excited to announce support for Google Compute Engine (GCE) N2 general purpose virtual machine (VM) types, and additional hardware configuration options powered by N2 custom machine types. N2 VMs leverage Intel 2nd Generation Xeon Scalable processors and provide a balance of compute, memory, and storage. N2 machine types also offer more than a 20% improvement in price-performance over the first-generation N1 machines.

Kibana creates easy ways to do powerful things with all of your data — to ask and answer questions and follow the flow of analysis. Many times the answer to your question requires calculations based on queried data. Formulas allow you to author your own metrics by combining multiple aggregated fields using math operations. In addition, moving through and replaying your data in time and space are powerful ways to gain historical context and understand additional insight about the present.

In an era where speed, productivity, and user experiences matter most what are the incident management capabilities managed service provider need most to grow, transform and mature their digital operations, processes and serve more organizations, faster and more efficiently. Many of today’s enterprises still have operations that are largely manual, reactive and lack the in-house resources and expertise to undertake a digital transformation initiative.

Function as a service (FaaS) offerings like AWS Lambda are a blessing for software development. They remove many of the issues that come with the setup and maintenance of backend infrastructure. With much of the upfront work taken out of the process, they also lower the barrier to start a new service and encourage modularization and encapsulation of software systems. Testing distributed systems and serverless cloud infrastructures.
