Serverless Architecture
Business Problem
The infrastructure of a financial services firm had not been optimized for performance, exposing it to critical vulnerabilities that could lead to security breaches. Built using Azure serverless functions, the firm struggled with slow performance and security vulnerabilities within the architecture, which impacted data processing speed, posed risks to operational efficiency and customer trust, and affected the reliability of its financial services.
Key challenges:
- Slow Data Processing: The firm’s existing infrastructure could not efficiently handle high-volume financial transactions and data processing tasks, even though it was flexible. This led to delayed processing and affected the overall reliability of service delivery.
Security Vulnerabilities: The absence of automated security tools and comprehensive security control left the system vulnerable to potential breaches, creating a high-risk environment for financial data.
System Performance: The system performance was inconsistent, fluctuating under load and leading to irregular slowdowns during peak times for transactions. This hindered the firm’s ability to provide reliable financial services to its customers.
- Operational Risks: Since probable security breaches or system downtimes could lead to regulatory penalties and the consequent loss of trust from customers, the inefficiencies and security flaws also increased operational risks.
The Approach
Curate’s consultants collaborated with the firm’s IT and security teams, conducted an in-depth analysis of the existing infrastructure, security, and operations, and designed a solution that would optimize the organization’s serverless architecture and integrate a robust security framework. This would result in enhancing data processing speed, mitigate security risks, and improve overall system performance.
Key components of the solution:
- Discovery and Requirements Gathering: The close collaboration between Curate and the form’s internal IT and Security teams helped assess the serverless architecture, identify performance bottlenecks, and evaluate the existing state of security, including:
Auditing the serverless environment through a comprehensive performance audit.
Carrying out detailed assessments to identify security gaps and vulnerabilities.
Improving performance, security, and operational efficiency by outlining the key requirements.
Creating optimized solutions by collaborating with external vendors such as Azure and security partners.
- Optimizing performance with Azure Functions: To enhance data processing speed and overall system performance, Cuarte focused on optimizing the serverless architecture of the firm.
Azure Functions Optimisation: Curate made sure that every function was optimized for speed and efficiency by fine-tuning the existing Azure Functions code. Curate enhanced serverless function performance under high transaction loads by optimizing memory allocation and decreasing cold start times.
Concurrency and Load Balancing: Curate implemented concurrency and load balancing strategies in the Azure environment to manage peak loads. Because of this, the system was able to automatically scale during times of high transaction volume, ensuring steady performance and quicker response times.
Data Flow Optimisation: Curate reduced latency and increased data processing throughput by streamlining the data flow between services. This resulted in real-time analytics and quicker financial transaction processing.
Enhancing Security with Veracode and Okta: Curate incorporated a strong security framework into the serverless environment to mitigate exposure to potential security risks.
Security Audit with Veracode: Curate carried out a comprehensive security audit to find flaws in the current codebase. Static and dynamic scanning tools from Veracode helped in identifying and reducing risks such as insufficient data protection, broken authentication, and injection flaws.
Multi-Factor Authentication (MFA) using Okta: Okta was used to strengthen access control and user authentication. Single sign-on (SSO) and MFA together decreased the possibility of unwanted access to sensitive financial data.
Automated Security Monitoring: Curate implemented automated monitoring systems to continuously evaluate the security of the system and enabled alerts for any suspicious behavior or unauthorized access attempts. The security team could then respond in real-time.
Stakeholder Engagement and Change Management:
Cross-Functional Collaboration: Curate ensured that all technical requirements were being met and that the solution was implemented without interfering with everyday operations through regular meetings with the firm’s IT, DevOps, and security teams.
Vendor Coordination: Curate collaborated with Azure and Veracode to ensure that the security features and serverless architecture of the platform were tailored to the particular risks faced by the company.
Training and Change Management: Curate provided the organization’s internal teams with comprehensive training and detailed documentation on how to use the new serverless architecture and security tools and ensure operational efficiency and long-term sustainability.
Business Outcomes
Improved Data Processing Speed
Curate significantly increased data processing performance by streamlining Azure Functions and optimizing the serverless architecture. This led to 40% lesser transaction processing times for the company which allowed for quicker and more reliable financial services.
Enhanced Security
The organization's risk of security breaches was significantly decreased by integrating Okta for MFA and Veracode for security auditing. Continuous protection against potential vulnerabilities was further ensured through automated security monitoring.
Decreased Operational Risks
By combining increased security with better system performance, operational risks were decreased. The company was better able to manage high transaction volumes without sacrificing data security or system dependability.
Sample KPIs
Here’s a quick summary of the kinds of KPI’s and goals teams were working towards**:
| Metric | Before | After | Improvement |
|---|---|---|---|
| Transaction processing time | 5 seconds | 3 seconds | 40% reduction |
| Security vulnerabilities identified | 10/year | 2/year | 90% reduction |
| Authentication success rate | 75% | 98% | 23% improvement |
| System uptime during peak loads | 92% | 99.9% | 7.9% reduction |
| Operational risks (security breaches) | 5/year | 2 delays/month | 0/year |
