The first version of our logger library optimized for storage by deduplicating facts and optimized for network i/o using different compression methods for each fact. Then we started hitting roadblocks while optimizing the query performance. Figure 2 shows components of Axion’s ETL and its interaction with the query client.

Many MongoDB clusters use storage-level snapshots to provide fast and reliable backups. Background story I recently worked with a company running a large four-shard MongoDB Enterprise Server database cluster on VMs on premises that decided to migrate to the Google Cloud Platform.

As with traditional storage, applications are writing to a shared storage environment which is necessary to support VM movement. It is the shared storage that often causes performance issues for data bases which are otherwise separated across nodes. The idea here is to simulate the two main storage workloads of a DB.

While you may assume a great majority of the cloud database deployments are run on AWS, Azure, or Google Cloud Platform, small to medium-sized businesses in particular are gravitating towards the developer-friendly cloud provider, DigitalOcean , for their hosting for MongoDB® needs.

But every organization I talked with, that is engaged in a k8s project, told me that in order for them to truly leverage k8s as a cloud native platform you need ALL of the following “ Monitoring as a Self-Service Capabilities ” (MaaSS) which aren’t covered by any of the open source or platform offerings: K8s cluster and pod health monitoring.

Web app testing : Optimized for mobile browsing and server-driven, the web apps should be tested for UI to ensure that all the elements of the app are aligned for different screens and resolutions. Since the mobile apps have limited storage space and power supply, test for memory utilization as well as battery usage.

There might have been one or two integrations with data or transaction services that resided elsewhere, but for the most part, we could validate user journeys with procedural test scripts, and have software testers run regressions and UAT cycles for any features that changed. Metrics and observability data hoarding. The Intellyx Take.

We ran empirical tests for scenarios of low and high request volumes, and the results are presented in the next section.

Additionally, many operational groups would like to be able to leverage functional testing scripts into production, saving hundreds, and potentially 1000’s of hours of rescripting time annually. There was some excitement on Apica’s concepts on reducing the overall costs of monitoring by utilizing containers for test executions.

It is limited by the disk space; it can’t expand storage elastically; it chokes if you run few I/O intensive processes or try collaborating with 100 other users. Our only option was to roll up our sleeves and build basic cloud file system components such as object store ourselves. Migration to cloud. Cloud Platform.

To optimize storage interally, you could use Dropbox’s new Lepton format for losslessly compressing JPEGs by an average of 22%. Plus, it’s even supported on Fastly’s edge cloud. Andy Davies did a similar research for HTTP/2 prioritization across browsers, CDNs and Cloud Hosting Services. kernels and later ( thanks, Yoav! ).
