Their “ State of OpenSource Security Report, 2020 ” found that the most common vulnerabilities are cross-site scripting vulnerabilities (18%), followed by malicious packages (13%). Snyk also reports that open-source software is a common entry point for vulnerabilities. Of these, WAF is much more commonly used today.
This becomes even more challenging when the application receives heavy traffic, because a single microservice might become overwhelmed if it receives too many requests too quickly. A service mesh is a dedicated infrastructure layer built into an application that controls service-to-service communication in a microservices architecture.
The fact is, Reliability and Resiliency must be rooted in the architecture of a distributed system. The email walked through how our Dynatrace self-monitoring notified users of the outage but automatically remediated the problem thanks to our platform’s architecture. And that’s true for Dynatrace as well.
Organizations that want a high-performance language with a great ecosystem for their applications often use Golang , an open-source programming language. Such additional telemetry data includes user-behavior analytics, code-level visibility, and metadata (including open-source data). Dynatrace news.

Data is proliferating in separate silos from containers and Kubernetes to opensource APIs and software to serverless compute services, such as AWS and Azure. Solving custom API observability with OpenTelemetry Because the bank group needed complete coverage for all API traffic, it wanted to standardize tracing on all API calls.
For example, an organization might use security analytics tools to monitor user behavior and network traffic. Security analytics must also contend with the multicomponent architecture of modern IT infrastructure. While it’s easy for analytics solutions to pinpoint symptoms, determining the communal source is much more difficult.
Opensource has also become a fundamental building block of the entire cloud-native stack. While leveraging cloud-native platforms, open-source and third-party libraries accelerate time to value significantly, it also creates new challenges for application security.
Opensource databases provide great foundations for high availability — without the pitfalls of vendor lock-in that can come with proprietary software. However, opensource software doesn’t typically include built-in HA solutions. They’re proven and ready-to-go.
Today we’re proud to announce the new Dynatrace Operator, designed from the ground up to handle the lifecycle of OneAgent, Kubernetes API monitoring, OneAgent traffic routing, and all future containerized componentry such as the forthcoming extension framework.
For retail organizations, peak traffic can be a mixed blessing. While high-volume traffic often boosts sales, it can also compromise uptimes. They also need a way to track all the services running on their distributed architectures, from multicloud environments to the edge. What is always-on infrastructure?
You’re getting all the architectural benefits of Grail—the petabytes, the cardinality—with this implementation,” including the three pillars of observability: logs, metrics, and traces in context. Opensource solutions are also making tracing harder. Logs on Grail Log data is foundational for any IT analytics.
Azure Traffic Manager. It enables you to use popular open-source frameworks such as Hadoop, Spark, and Kafka in Azure cloud environments. Azure Front Door enables you to define, manage, and monitor the global routing for your web traffic by optimizing for best performance and quick global failover for high availability.
We started seeing signs of scale issues, like: Slowness during peak traffic moments like 12 AM UTC, leading to increased operational burden. Meson was based on a single leader architecture with high availability. At Netflix, the peak traffic load can be a few orders of magnitude higher than the average load.
We also highlight interesting broader events such as regional traffic evacuations and nearby deployments , information that is vital to understanding health holistically. Telltale uses a variety of signals from multiple sources to assemble a constantly evolving model of the application’s health: Atlas time series metrics.
PostgreSQL is a free and opensource object-relational database management system (ORDBMS) that has existed since the mid-1990s. Opensource and free PostgreSQL is an opensource database, which means it is free to use, distribute, and modify. Download Percona Distribution for PostgreSQL Today!
There are several opensource CDC projects, often using the same underlying libraries, database APIs, and protocols. No locks on tables are ever acquired, which prevent impacting write traffic on the source database. Hence, downstream consumers have confidence to receive change events as they occur on a source.
Load balancing : Traffic is distributed across multiple servers to prevent any one component from becoming overloaded. Load balancers can detect when a component is not responding and put traffic redirection in motion. When planning your database HA architecture, the size of your company is a great place to start to assess your needs.
