A Service Level Agreement (SLA) isn’t just a list of services, metrics, and penalties. It is a crucial part of your Managed Services Agreement (MSA). MSP SLAs help determines expectations and how to measure them, so you can keep clients satisfied and eliminate potential disputes. By technative.io.

This is very detailed article covering amongst others:

• What is an SLA?
• Why do you need an SLA?
• SLA overview: How to write a Service Level Agreement?
• Service level agreement best practices
• Most common SLA mistakes

An SLA might not be the most exciting part of MSP work, but it is essential for building solid client relations. In this article, you will find tips on how to draft a thorough and clear SLA agreement. Producing a robust Service Level Agreement (SLA) begins with a practical approach that can protect both customers and the MSP. A well-written service-level agreement will help you build a strong relationship with your clients that will last for a long time. Nice one!

AWS recently announced a distributed map for Step Functions, a solution for large-scale parallel data processing. Optimized for S3, the new feature of the AWS orchestration service targets interactive and highly parallel serverless data processing workflows. By Renato Losio.

The new distributed map state allows writing Step Functions to coordinate large-scale workloads, iterating over millions of objects on S3, for example, logs, images, or CSV files. While AWS previously supported Step Function’s map state to execute the same processing steps for multiple entries in a dataset, it was limited to 40 parallel iterations.

The distributed map stops reading after 100 million items and supports JSON or CSV files of up to 10GB. Rafal Wilinski, founder of Dynobase, shares a CDK-based PoC of a migrations framework taking advantage of the new feature and comments: Step Functions Distributed Maps are awesome. Combined with DynamoDB Parallel scans, they enable blazingly fast, whole-table data migrations and transformations. Interesting read!

YAML is a well-known language for generating JSON files, but as we have been generating Docker Compose for integration tests, we’ve found Jsonnet to be better. Before we discuss both languages, keep in mind that this piece is strictly to discuss the use of each language when generating JSON. By Colin Mo.

The article walks over:

• YAML pros
• YAML cons
• Jsonnet pros
• Jsonnet cons
• Examples

Jsonnet is a data serialization format and a programming language. As a superset of JSON, Jsonnet can parse any valid JSON file and add extra functionality to it. Jsonnet is specifically designed to easily work with JSON data, especially in large and complex projects, by providing features such as variables, conditionals, and loops.

On of disadvantage of YAML is its lack of support for certain types of data, such as dates and times. While YAML can handle numbers and strings, it does not have built-in support for more complex data types, which can make it more difficult to work with certain types of data. Interesting read!

Deno Fresh WASM is pretty easy to set up, just by adding a single dependency to your project. This lets you write code in Rust, compile it to WASM and then use that generated module in your Deno project. By Rodney Lab.

The article then covers:

• Setting up the project for Rust WASM
• Rust code
• Deno Fresh WASM: Rust source
• Compiling the module
• Using the module

In the post we have had a whistle-stop tour of setting up your first Deno WASM project. In particular, we saw how to use wasmbuild to quickly add a Rust WASM module to your Deno project, how to add console logs in your WASM Rust code, some basic Rust image manipulation. Excellent read with code in GitHub repo provided!

Over the course of the last few months, we at Memgraph have been working on something that we believe could be helpful with classical graph prediction tasks. With our latest newborn query module, you will have the option of performing both label classification and link prediction. By Antonio Filipovic.

The following is explained:

• Graph neural networks
• Temporal graph networks
• Amazon data example
• Exploring an Amazon data network in Memgraph

You probably already know that a graph consists of nodes (vertices) and edges (relationships). Every node can have its feature vector, which essentially describes that node with a vector of numbers. We can look at this feature vector as the representation vector of each node, also called embedding of the node. To avoid getting lost in technical details, graph neural networks work as a message passing system, where each node aggregates feature representations of its 1-hop neighbors.

Plenty of examples and code is provided as well in the article. Good read!

While more and more teams are adopting Kubernetes as their standard container orchestration technology, cost insight is lacking. Teams often don’t know how much they’re spending, where in their organization they are spending, or what is driving their infrastructure cost increases. OpenCost helps alleviate this problem by bringing real-time cost monitoring to Kubernetes workloads with a solution that encompasses both an open specification and an open source project. By Mark Poko, JuanJo Ciarlante.

• How Grafana Labs uses OpenCost
  • Getting more accurate insight into vCPU and memory cost
  • Monitoring costs of a multi-cluster architecture
• How Grafana Labs will contribute to the OpenCost OSS project
  • Observability
  • Ease of use
  • Performance

To get started with OpenCost and cost observability, you can find the OpenCost code in GitHub and check out the OpenCost documentation. Nice one!

Global energy demand has rapidly increased over the last few years and looks set to continue accelerating at such a pace.

This is the journey of author to create serverless solution written in Go which enabled him to be notified about best currency exchange rates for his small business. Nice one!

Having a personal Forex bot is very useful only if it is always up and running. AWS Lambda is a virtually free solution to host a simple program like mine (or even small microservice architectures), so I refactored my code to run as a serverless function. By Loris Occhipinti.

Sometimes, a client may be willing to pay you in its local currency only. Of course, this is a slight inconvenience but, after all, setting up a multicurrency account is usually easy and inexpensive, so it might be best to accept the arrangement and plan to convert the money later.

The strategy for bot was simple: sending a notification every 2 hours with the current rate and the potential gain or loss I could make at that point in time. The most critical part was getting correct, timely data about exchanges: there are myriads of APIs that can help with this,

This is the journey of author to create serverless solution to enable hi to convert currencies at most favorable terms and rates for his small business. Nice one!
