A cloud application is software hosted in a cloud environment and accessed via a web browser or a cloud app, without the need to install it locally on a device. Unlike desktop applications, cloud-based applications allow users to access applications and data from anywhere in the world. They also provide automatic updates, high scalability, and flexible cloud infrastructure, making them well suited for modern business operations.
Cloud computing is a model for delivering IT resources, such as cloud servers, computing power, cloud storage, and software applications, as cloud services. Thanks to cloud computing services, cloud computing applications can dynamically leverage resources from cloud service providers like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform. This approach enables faster deployment, lower infrastructure costs, and greater flexibility in responding to changing business needs.
Sii designs and develops cloud-native applications and SaaS applications (software as a service). Our cloud application development services include both extending enterprise platforms such as Microsoft 365, Salesforce, ServiceNow, SAP, and Atlassian, as well as building dedicated cloud-based applications tailored to specific business processes and organizational requirements.
Yes. Security is a core element of cloud application development at Sii. We apply advanced security measures, including protection against unauthorized access, data encryption, backup and recovery mechanisms, and compliance with regulatory requirements. By working with leading cloud providers, we ensure a secure cloud environment and a high level of protection for data stored in the cloud.
The SaaS model (software as a service) allows organizations to use cloud applications without managing their own cloud infrastructure. SaaS applications are accessed over the internet, with automatic updates and scalable cloud resources handled by the cloud service provider. This model works best when rapid deployment, real-time collaboration, and access to applications from any device are key business priorities.
Yes. Sii delivers cloud application development projects in a multi-cloud and hybrid cloud model, using AWS, Microsoft Azure, and Google Cloud. This approach improves reliability and resilience, supports different types of cloud environments, and allows organizations to choose the most suitable cloud platform based on business, regulatory, and cost requirements.
Application modernization involves adapting existing desktop or legacy applications to run in the cloud. This process may include re-platforming, code refactoring, containerization, or migrating applications to a SaaS-based model. Sii analyzes applications, selects the optimal cloud application development process, and ensures continuity of operations throughout the transition to cloud technology.
Yes. Cloud applications enable real-time collaboration and seamless access to applications and data from any location and any device with internet access. Cloud-based applications support remote, hybrid, and distributed teams by allowing users to work together efficiently across devices such as laptops, tablets, and mobile platforms.
Sii conducts performance testing, analyzes cloud infrastructure usage, and configures autoscaling and optimal resource allocation across cloud application servers. We also apply FinOps practices to help manage cloud services costs and maximize the business value of investments in cloud computing applications.
Sii’s Cloud Applications services are used by organizations in finance, manufacturing, retail, logistics, telecommunications, and regulated industries. Our cloud solutions support critical business processes, data management, and secure use of cloud applications at enterprise scale.
