This is where large-scale system migrations come into play.
How To Design For High-Traffic Events And Prevent Your Website From Crashing How To Design For High-Traffic Events And Prevent Your Website From Crashing Saad Khan 2025-01-07T14:00:00+00:00 2025-01-07T22:04:48+00:00 This article is sponsored by Cloudways Product launches and sales typically attract large volumes of traffic.
In this article, we’ll dive deep into the concept of database sharding, a critical technique for scaling databases to handle large volumes of data and high levels of traffic. We’ll start by defining what sharding is and why it’s essential for modern, high-performance databases.
Aside from the huge surge in internal application usage, businesses are also witnessing increased levels of user traffic to their applications. Facilitating an understanding of traffic patterns and potential traffic spikes helps maintain customer experience. One example of these surges was from an unemployment application.
Incremental Backups: Speeds up recovery and makes data management more efficient for active databases. Improved JSON Handling & Security: Improved logical replication and the new MAINTAIN privilege give database administrators more control and flexibility. Start your free trial today!
Over the last two month s, w e’ve monito red key sites and applications across industries that have been receiving surges in traffic , including government, health insurance, retail, banking, and media. The following day, a normally mundane Wednesday , traffic soared to 128,000 sessions.
Where you decide to host your cloud databases is a huge decision. But, if you’re considering leveraging a managed databases provider, you have another decision to make – are you able to host in your own cloud account or are you required to host through your managed service provider? Where to host your cloud database?
a Fast and Scalable NoSQL Database Service Designed for Internet Scale Applications. Today is a very exciting day as we release Amazon DynamoDB , a fast, highly reliable and cost-effective NoSQL database service designed for internet scale applications. Werner Vogels weblog on building scalable and robust distributed systems.
Most applications communicate with databases to, for example, pull a catalog entry or submit a new record when an order is placed. To achieve this, there must be a healthy connection between the application and the database. Application servers use connection pools to maintain connections with the databases that they communicate with.
When it comes to enterprise-level databases, there are several options available in the market, but PostgreSQL stands out as one of the most popular and reliable choices. PostgreSQL is a free and open source object-relational database management system (ORDBMS) that has existed since the mid-1990s.
A common question that I get is why do we offer so many database products? To do this, they need to be able to use multiple databases and data models within the same application. Seldom can one database fit the needs of multiple distinct use cases. Seldom can one database fit the needs of multiple distinct use cases.
We thus assigned a priority to each use case and sharded event traffic by routing to priority-specific queues and the corresponding event processing clusters. This separation allows us to tune system configuration and scaling policies independently for different event priorities and traffic patterns.
In case of a spike in traffic, you can automatically spin up more resources, often in a matter of seconds. Likewise, you can scale down when your application experiences decreased traffic. For example, as traffic increases, costs will too. Analyze your resource consumption and traffic patterns.
To make data count and to ensure cloud computing is unabated, companies and organizations must have highly available databases. A basic high availability database system provides failover (preferably automatic) from a primary database node to redundant nodes within a cluster. HA is sometimes confused with “fault tolerance.”
This opens the door to auto-scalable applications, which effortlessly matches the demands of rapidly growing and varying user traffic. Containers can be replicated or deleted on the fly to meet varying end-user traffic. In production, containers are easy to replicate. What is Docker? Networking.
Resource consumption & traffic analysis. Database & functional migration. What is the network traffic going to be between services we migrate and those that have to stay in the current data center? How much traffic is sent between two processes hosting a certain service? Step 4: Smart Database Migration.
Andreas Andreakis , Ioannis Papapanagiotou Overview Change-Data-Capture (CDC) allows capturing committed changes from a database in real-time and propagating those changes to downstream consumers [1][2]. In databases like MySQL and PostgreSQL, transaction logs are the source of CDC events. Designed with High Availability in mind.
Possible scenarios A Distributed Denial of Service (DDoS) attack overwhelms servers with traffic, making a website or service unavailable. Possible scenarios A retail website crashes during a major sale event due to a surge in traffic. These attacks can be orchestrated by hackers, cybercriminals, or even state actors.
Database monitoring. This ensures the database queries are performant, while also identifying host problems. For example, uptime detection can identify database instability and help to improve mean time to restoration. Website monitoring examines a cloud-hosted website’s processes, traffic, availability, and resource use.
In addition to providing visibility for core Azure services like virtual machines, load balancers, databases, and application services, we’re happy to announce support for the following 10 new Azure services, with many more to come soon: Virtual Machines (classic ones). Azure Traffic Manager. Azure Batch. Azure DB for PostgreSQL.
It comes as no surprise that Python developers commonly leverage MongoDB hosting , the most popular NoSQL database , for their deployments due to its flexible nature and lack of schema requirements. It is also recommended that SSL connections be enabled to encrypt the client-databasetraffic. Testing Failover Behavior.
It’s a common scenario to have a Percona Monitoring and Management (PMM) server running on Kubernetes and also desire to monitor databases that are running outside the Kubernetes cluster. The Ingress NGINX Controller is one of the most popular choices for managing the inbound traffic to K8s.

In databases like MySQL and PostgreSQL, transaction logs are the source of CDC events. Designed with High Availability in mind.
Managing High Availability (HA) in your PostgreSQL hosting is very important to ensuring your database deployment clusters maintain exceptional uptime and strong operational performance so your data is always available to your application. Standby servers are activated when the primary server fails.
Such scans enable teams to detect SQL injection attacks that allow someone to maliciously inject code into a database query. Scanning the runtime environment of your services can help to identify unusual network traffic patterns. National Vulnerability Database (NVD) lists over 175,000 known vulnerabilities.
Dynatrace PurePath technology captures and analyzes transactions end to end across every tier of your application technology stack, from the browser all the way down to the code and database level. Turnkey cluster overload protection with adaptive traffic management and control. Impact on disk space.
These include traditional on-premises network devices and servers for infrastructure applications like databases, websites, or email. ActiveGate also optimizes traffic volume in your network and serves as a secure relay layer in protected networks and DMZs.
WAFs protect the network perimeter and monitor, filter, or block HTTP traffic. Compared to intrusion detection systems (IDS/IPS), WAFs are focused on the application traffic. RASP solutions sit in or near applications and analyze application behavior and traffic.
Production Use Cases Real-Time APIs (backed by the Cassandra database) for asset metadata access don’t fit analytics use cases by data science or machine learning teams. Existing data got updated to be backward compatible without impacting the existing running production traffic.
These four dimensions apply to any layer in the technical stack, such as front-end, databases, and external services. The rows thereafter report the health of front-end, databases, and external services. For example, saturation could be CPU time per request, queue size, used database connections, and API throttle limit utilization.
Infrastructure Optimization: 100% improvement in Database Connectivity. Think of a user login which requires your back-end systems to validate user credentials and query required user profile information from the backend databases. Too much data requested from a database, e.g. Request all and filter in memory.
Continuously monitoring application behavior, network traffic, and system logs allows teams to identify abnormal or suspicious activities that could indicate a security breach. This approach can determine malicious activity and block it by monitoring the flow of data within the application, all the way from the user to the database.
Think about items such as general system metrics (for example, CPU utilization, free memory, number of services), the connectivity status, details of our web server, or even more granular in-application tasks like database queries. Database monitoring Once more, under Applications & Microservices, we’ll also find Databases.
MongoDB is the #3 open source database and the #1 NoSQL database in the world. It’s a cross-platform document-oriented database that uses JSON-like documents with schema, and is leveraged broadly across startup apps up to enterprise-level businesses developing modern apps. minutes of downtime in one year. MongoDB Replica Sets.
One is the currently-running production environment receiving all user traffic (let’s say the “blue” one), the other is a clone of it (“green”), but idle. Both use the same database back-end and app configuration. Once the testing results are successful, application traffic is routed from blue to green.
On the first node, Patroni initializes the database, obtains the leader lock from DCS, and ensures the node is being run as the master. All of these tests were performed while the application was running and inserting data to the PostgreSQL database. Corosync traffic was blocked on the master server. Standby Server Tests.
Depending on how it is configured, Redis can act like a database, a cache or a message broker. It’s important to note that Redis is a NoSQL database system. 8 ranked database on DB-Engines with a score of 144.08. Let us take a closer look at the data types that exist in Redis. 8,759 developers stated using Redis on StackShare.
Data powers everything, and unlike coal and coal combustion, data and databases aren’t going away. In this blog, we’ll focus on the elements of database backup and disaster recovery, and we’ll introduce proven solutions for maintaining business continuity, even amid otherwise dire circumstances.
This unified approach enables Grail to vault past the limitations of traditional databases. And without the encumbrances of traditional databases, Grail performs fast. “In In most cases, especially with more complex queries, Grail gives you answers at five to 100 times more speed than any other database you can use right now.”
Migrating a proprietary database to open source is a major decision that can significantly affect your organization. Today, we’ll be taking a deep dive into the intricacies of database migration, along with specific solutions to help make the process easier.
Whether you need to make sure that your SQL database is listening on port 1433 even when there is no traffic, that your switch is responding to a ping or that your DNS server is up and running, the more devices you proactively monitor, the quicker you can react to unforeseen events.
We also highlight interesting broader events such as regional traffic evacuations and nearby deployments , information that is vital to understanding health holistically. Regional traffic evacuations. A regional traffic shift means one region ends up with zero traffic while another region has double.
Central to this infrastructure is our use of multiple online distributed databases such as Apache Cassandra , a NoSQL database known for its high availability and scalability. Over time as new key-value databases were introduced and service owners launched new use cases, we encountered numerous challenges with datastore misuse.
