Accept traffic from services outside the private network such as clusters.Traffic control, also called traffic routing or traffic shaping refers to the control of where traffic goes and how it gets there. Ingress traffic controllers are a solution to managing incoming data traffic. While egress filtering is needed to ensure security, it's important to manage ingress traffic too. A data storage client that's outside the private network reading data from a cloud storage bucket within the private network perimeter.An API client located outside the private network that accesses resources within the private network perimeter.Note that this is traffic transferred to the private network, not response data from requests originating from the private network - ingress is not response traffic.Įxamples of ingress scenarios within a cloud service environment: In the cloud, ingress is unfiltered traffic sent from the public internet. What is Data Ingress?Īs you might expect, ingress refers to data traffic that enters a private network from the public internet or another external location. It enables them to block the transfer of sensitive data outside the internal network and verify or block high-volume data transfers if necessary. Egress filtering can be used to identify these threats.Įgress filtering allows the organization to create rules for egress traffic management. Organizations can perform monitoring to mitigate potential threats from egress traffic and identify anomalies and malicious activity. Intelligent traffic management systems are becoming a necessary solution to managing complex container and cluster environments. Therefore, with the increased use of microservice architecture, it's becoming more important for organizations to have advanced traffic management and security tools. This interception or theft is often referred to as data exfiltration. Malicious actors are constantly on the lookout for unprotected data, snooping on data in transit, intercepting, and stealing data.Ĭriminals will use any number of techniques to achieve this such as spreading malware or disguising network traffic. Data transferring outside of a private network to the public internet is susceptible to attack. The process of data egress has intrinsic threats. A data storage client that copies data from one data store (bucket) which is inside the network to another data store (bucket) that is outside the perimeter.An API client within a service perimeter calls an operation where the resource is outside the network perimeter.It's commonly used by cloud service providers as a measurement of traffic volume.Įxamples of egress scenarios within a cloud service environment: The term egress is often used to describe the volume of traffic leaving a network to external networks. This occurs all the time in organizations via email, file uploads, or HTTP and FTP transfers. In the cloud, egress refers to traffic that leaves a private network and transfers to the public internet. Egress is any situation where data exits an entity or network boundary. It's important to note that egress also refers to data shared to an external network via physical devices such as USB drives or external hard drives. Egress traffic is outbound traffic being shared externally. So what does egress mean when talking about cloud technology? In simple terms, egress refers to data leaving one network and transferring to an external network location. These terms are also used to describe network traffic flow. Ingress is the act of entering and egress is the act of exiting. Ingress and egress refer to them as entries and exits.
