Technical debt is slowing you down, but the application remains critical<\/h2>\n

Code is ageing, skills are becoming harder to find and vulnerabilities are increasing. Moving to the cloud seems necessary, but the application is too important to be stopped. A complete rewrite is expensive and creates concern. You need a partner who understands the business value of the existing application and knows how to modernize it without disruption.<\/span>[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” bottom_padding=”100″ text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” row_position_desktop=”default” row_position_tablet=”inherit” row_position_phone=”inherit” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” gradient_type=”default” shape_type=””][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” flex_gap_desktop=”10px” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”]

01<\/div>

A key application that has become difficult to develop<\/h3>

Code consists of many layers added over time, documentation is incomplete and every change takes longer. Business users have to wait, maintenance costs increase and every update creates a risk of regression.<\/p><\/div>

<\/div><\/div>
02<\/div>

Vulnerabilities and dependencies continue to increase<\/h3>

Old framework versions, unsupported libraries and limited security hardening: security debt becomes a risk that neither the IT department nor senior management can leave unresolved in a stricter regulatory environment.<\/p><\/div><\/div>

03<\/div>

Cloud migration: necessary but risky?<\/h3>

Moving away from on-premise hosting, replacing ageing servers and adapting the application to the cloud: the main challenge is not only technical. It is operational. How can you migrate without stopping the service provided to users and customers?<\/p><\/div>

Strategic vision<\/span><\/p>\n

Understand the existing application before changing it: our step-by-step modernization strategy<\/h2>\n

An old application is not only a block of outdated code. It also includes business rules, established uses and operational value that is often underestimated. Before we suggest a roadmap, we take the time to understand what needs to stay and what needs to go.<\/p>\n

Our Digital Factory works with the main technologies used in the application systems of large organizations: .NET, PHP, Java, Angular, and others. Depending on the situation, we restructure the code, divide the application into modules, or rewrite it in stages using long-term technologies.<\/p>\n

Our approach follows one simple principle: modernizing an application must give you more control, not create a new dependency. The source code and project deliverables belong to you. You keep control of business continuity, security and maintainability, and remain free to develop your application with Synidia, your own teams, or another partner.<\/p>\n[\/vc_column_text][divider line_type=”No Line” custom_height=”20″][vc_column_text css=”” text_direction=”default”].NET, PHP, Java, Angular<\/span>OWASP standards<\/span>Cloud migration in stages<\/span>[\/vc_column_text][\/vc_column][vc_column column_padding=”padding-2-percent” column_padding_tablet=”inherit” column_padding_phone=”no-extra-padding” column_padding_position=”left-right” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ background_image=”948″ background_image_type=”default” background_image_position=”center center” background_image_stacking=”default” enable_bg_scale=”true” background_image_loading=”default” column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”15px” column_link_target=”_self” column_position=”default” el_class=”image_fond” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/2″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid” column_padding_type=”default” content_layout=”default” gradient_type=”default”][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” top_padding=”80″ left_padding_desktop=”100″ right_padding_desktop=”100″ left_padding_phone=”0″ right_padding_phone=”0″ text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” row_position_desktop=”default” row_position_tablet=”inherit” row_position_phone=”inherit” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” gradient_type=”default” shape_type=””][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” centered_text=”true” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid” column_padding_type=”default” content_layout=”default” gradient_type=”default”][vc_column_text css=”” text_direction=”default”]Controlled modernization<\/span><\/p>\n
