A proxy is a cloud-based system between your device and a web server, SaaS application, or data centre. Instead of relying on a traditional data centre, it uses a cloud server to authenticate and forward user requests to web servers for processing.
Read below to learn all about Cloud Proxies!
Cloud Proxy: Meaning
Cloud Proxy serves as an intermediary between the client and the internet. It acts as a middleman, shielding your IP address and location from malicious hackers who may attempt to monitor your network activity or steal sensitive data.
Proxy servers receive your internet requests, communicate with web servers, and relay the responses to your web browser (such as Chrome, Safari, Firefox, or Microsoft Edge). Managed by a third party, proxy servers verify incoming requests and forward them to others for processing.
Depending on the proxy type, you may be visible or hidden to the servers processing the proxy and your internet service provider. Still, your presence remains concealed from the web servers hosting the requested resources.
Proxy servers have different functionalities, security levels, and privacy options to cater to various needs, use cases, or company policies. Using a proxy is generally considered the safest method for inspecting online traffic.
How Does a Cloud Proxy Work?
A Cloud-Based Proxy facilitates internet traffic flow to a specific online destination. It acts as a middleman between your computer and the website, allowing data to be received through the proxy server.
When integrated with an organisation's authentication service, a cloud proxy becomes part of the traffic flow without requiring an agent. This seamless setup ensures a user-friendly experience, automatically redirecting incoming traffic to managed cloud applications through the proxy.
Outlined below are the simple steps detailing how a Cloud Proxy service works:
- The client sends a request, which is intercepted by the cloud proxy.
- If applicable, the cloud proxy forwards the request to a firewall.
- The firewall either blocks the request or passes it on to the server.
- The server sends a response through the firewall to the proxy.
- The cloud proxy forwards the response to the client, making it appear that the client and server communicate directly.
What are the Challenges with Traditional Appliance-Based Proxies?
Like you, many other internet users also use proxy servers to access their favourite websites.
As a result, proxy servers handle a significant amount of traffic, accommodate data from numerous users' devices and facilitate communication between those devices and the intended servers.
However, proxy servers often operate with limited bandwidth due to the high traffic volume, leading to latency issues and slower internet speeds.
Deploying and maintaining hardware-based proxy appliances can be costly, requiring significant initial investments for purchasing the appliances themselves and associated infrastructure and licensing costs.
Additionally, ongoing maintenance, upgrades, and support services contribute to the total cost of ownership, making it a potential financial challenge for smaller businesses with limited budgets.
Proxy servers have compatibility limitations with certain network protocols, which restricts the range of applications that can be supported and secured by the network.
Proxy agents must be specifically developed for each new application to address this issue. These agents filter or route a network protocol through the firewall, ensuring compatibility and appropriate security measures.
- Single Point of Failure
Appliance-based proxies present a single point of failure in the network architecture. If the proxy appliance experiences a hardware failure or any other technical issue, it can disrupt the entire network's functionality and accessibility.
This vulnerability can result in downtime, loss of productivity, and potential security risks if there are no backup measures to handle such failures.
Top 4 Cloud Proxy Benefits
- Heightened Scalability: As modern work environments become increasingly mobile and distributed, users often operate from remote locations, away from the traditional enterprise network.
Cloud-based proxy solutions are designed to scale globally, accommodating the needs of constantly moving users. Users can access the required resources with consistent performance and reliability regardless of their geographical location.
- Cost Savings: By offering an alternative to hardware-based proxies, which often come with high upfront and maintenance costs, the solution enables organisations to achieve significant cost savings.
It eliminates the need for investing in expensive hardware appliances, reduces IT spending, and allows for more efficient allocation of resources.
- Optimised User Experience: The solution prioritises delivering a smooth and seamless user experience. Even when decrypting and analysing encrypted network traffic, it ensures that end users do not experience noticeable latency or delays.
This allows users to work efficiently and effectively without interruptions caused by security measures.
- Enhanced privacy and security: The solution provides an added layer of privacy and security by keeping the server hidden from external visibility. This protects the organisation's infrastructure and sensitive data from potential threats.
Additionally, it ensures the necessary balance between functionality and security.
What are the Cloud Proxy Use Cases?
Cybersecurity and Data Protection
In the cloud environment, the risk of cyber threats is higher, but proxies provide network users with anonymity by routing incoming messages through a proxy gateway. Encryption techniques are utilised to secure the messages during transmission.
Web servers are susceptible to crashes due to excessive request loads. Proxies address this issue by distributing the load among servers closer to the clients, ensuring a balanced workload and safeguarding the main server.
Load balancers employ reverse proxy techniques to distribute requests and maintain anonymity, protecting the web server from potential attackers.
For business professionals and data analysts who require large amounts of data from diverse sources, scraping data stored in the cloud becomes more efficient.
Proxies are essential in this process, allowing unlimited high-speed data scraping without IP restrictions and facilitating seamless storage in a virtual database.
Businesses often need to analyse extensive data from global sources to improve sales strategies. Cloud-based scraping tools can gather and process data from various sites without geographic limitations.
Cloud proxies serve as a solution to overcome IP blocks and geo-block issues, enabling unrestricted access to data for effective market research.
Another challenge with traditional appliance-based proxies is the lack of reverse proxy capabilities. A reverse proxy server helps load balancing and protects web servers from direct exposure to the internet.
However, traditional appliance-based proxies often lack the reverse proxy functionality, limiting their ability to handle and distribute incoming requests to the appropriate servers efficiently.
