Is ActiveMQ an ESB?

Apache TomEE ActiveMQ is the default JMS provider. Mule is an Enterprise Service Bus (ESB) messaging framework. It is a scalable, highly distributable object broker that can seamlessly handle interactions with services and applications using disparate transport and messaging technologies.

Is ActiveMQ a message bus?

It works as a message-oriented middleware (MoM). ActiveMQ is designed to send messages between two or more applications, just like all message-oriented middleware.

Is ActiveMQ a JMS provider?

Apache ActiveMQ is an open source message broker written in Java together with a full Java Message Service (JMS) client. It provides "Enterprise Features" which in this case means fostering the communication from more than one client or server.

What is the difference between ESB and JMS?

JMS is a protocol for communicating with an underlying messaging layer. ESB operates at a higher level, offering integration with multiple technologies and protocols, one of which would be JMS, in a uniform way that makes management of complex flows much simpler.

What protocol does ActiveMQ use?

0 ActiveMQ has support for automatic wire protocol detection over TCP, SSL, NIO, and NIO SSL. OpenWire, STOMP, AMQP, and MQTT are supported. For details see the AUTO Transport Reference.

What is ActiveMQ and Why Would I Use it?

What is the difference between Kafka and ActiveMQ?

Kafka is way faster than ActiveMQ. It can handle millions of messages per sec. ActiveMQ supports both message queues and publishes/subscribe messaging systems. On the other hand, Kafka is based on publish/subscribe but does have certain advantages of message-queues.

What is difference between RabbitMQ and ActiveMQ?

ActiveMQ is used in enterprise projects to store multiple instances and supports clustering environments based on the JMS messaging specification. RabbitMQ is a message broker which is executed in low-level AMQP protocol and acts as an intermediator between two application in the communication process.

What is the difference between JMS and MQ?

MQ can act as a native queue mechanism or a transport for JMS messages. The difference being that JMS messages have some standard header fields at the begining of the message buffer and "native" mq messages contain just the data your program sent to the buffer.

Is ActiveMQ a message queue?

Written in Java, ActiveMQ translates messages from sender to receiver. It can connect multiple clients and servers and allows messages to be held in queue, instead of requiring both the client and server to be available simultaneously in order to communicate.

Is ActiveMQ distributed?

The members of the unit are usually distributed across multiple servers within a cluster, with each queue member belonging to a separate JMS server. AMQ provides network connectors to connect AMQ servers as a cluster.

Who supports ActiveMQ?

Savoir Technologies, Inc provides enterprise consulting, training and support for ActiveMQ “Classic”, ActiveMQ Artemis, and a host of other Apache service containers.

Does ActiveMQ use Log4j?

ActiveMQ “Classic” does use Log4j for logging, but the latest versions (i.e. 5.15. 15 and 5.16. 3) use Log4j 1.2. 17 which is not impacted by CVE-2021-44228.

What is spring boot ActiveMQ?

spring-boot-starter-activemq : It provides all the required dependencies to integrate JMS and activemq with spring boot. activemq-broker : This provides embedded activemq in spring boot application. But since, we will be configuring our activemq outside the application we have commented it for time being.

Is ActiveMQ pub sub?

In a publish/subscribe (pub/sub) product or application, clients address messages to a topic, which functions somewhat like a bulletin board. Subscribers can receive information, in the form of messages, from publishers.

Is ActiveMQ scalable?

1. Vertical scaling. Vertical scaling is a technique used to increase the number of connections (and therefore load) that a single ActiveMQ broker can handle. By default, the ActiveMQ broker is designed to move messages as efficiently as possible to ensure low latency and good performance.

How many messages can ActiveMQ handle?

To get around this limitation, ActiveMQ introduced a paging cache - for all message stores (except the memory store) to get the best of both worlds - great performance and the ability to hold 100s of millions of messages in persistent store.

Is RabbitMQ a JMS?

RabbitMQ is not a JMS provider but includes a plugin needed to support the JMS Queue and Topic messaging models. JMS Client for RabbitMQ implements the JMS 1.1 specification on top of the RabbitMQ Java client, thus allowing new and existing JMS applications to connect to RabbitMQ.

Is IBM MQ a JMS provider?

IBM MQ classes for JMS is a JMS provider that implements the JMS interfaces for IBM MQ and also provides the following two sets of extensions to the JMS API: IBM MQ JMS extensions.

Is IBM MQ a JMS?

IBM® MQ classes for JMS is the JMS provider that is supplied with IBM MQ. IBM MQ classes for JMS implements the interfaces defined in the javax. jms package, and also provides two sets of extensions to the JMS API.

Is ActiveMQ push or pull?

ActiveMQ will push as many messages to the consumer as fast as possible, where they will be queued for processing by an ActiveMQ Session. The maximum number of messages that ActiveMQ will push to a Consumer without the Consumer processing a message is set by the pre-fetch size.

Does ActiveMQ support MQTT?

ActiveMQ supports the MQTT protocol and will automatically map between JMS/NMS and MQTT clients. MQTT is a machine-to-machine (M2M) publish/subscribe messaging transport.

Is ActiveMQ compatible with RabbitMQ?

Yes, it is possible. The ActiveMQ and RabbitMQ are two broadly deployed message brokers. The main differentiation is ActiveMQ works as an open-source multi-protocol message broker in Java whereas RabbitMQ has written in Erlang. Both ActiveMQ and RabbitMQ are used in wide industrial applications.

Is ActiveMQ synchronous?

The default setting for ActiveMQ is that all persistent messages outside of a transaction are sent to a broker are synchronous.

Is Kafka better than MQ?

Throughput: Kafka is recommended for applications that demand high throughput or interaction with a big data stack. On the other hand, IBM MQ is best suited for applications that require a high level of reliability and cannot tolerate message loss.

Is Kafka a message queue?

We can use Kafka as a Message Queue or a Messaging System but as a distributed streaming platform Kafka has several other usages for stream processing or storing data.
